Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other embodiments can also be obtained based on these drawings.

[0055] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field based on this application are within the scope of protection of this application.

[0056] First, the professional terms that may be used in the embodiments of this application are explained:

[0057] Line chart: A chart that connects data points with broken lines. The horizontal axis is called the X-axis (usually used to represent different comparison dimensions, such as 'time'), and the vertical axis is called the Y-axis (usually used to represent data values, such as 'times').

[0058] X-axis basic unit: The smallest unit used to represent the horizontal axis in a chart. (For example, if a horizontal axis is composed of 100 X-axis basic units, the smallest unit of the horizontal axis is 1 / 100).

[0059] Data basic unit: used to represent the actual minimum granularity of data (for example, the chart shows data within 10 minutes, where one data is generated every 10 seconds. In this case, one data basic unit is the actual data generated. The entire chart contains 60 data basic units. This does not mean that one X-axis basic unit corresponds to one data basic unit. There may be two X-axis basic units to display one data basic unit).

[0060] Compression ratio: This represents the ratio of data units to X-axis units. (For example, if six X-axis units are used to display one data unit, the compression ratio is 1 / 6. The maximum compression ratio is 1, meaning one X-axis unit is used to display one data unit.)

[0061] Partition: A regional noun that has different characteristics between partitions but the same characteristics within a partition.

[0062] Virtual values: In partitions with a compression ratio less than 1, there are some non-existent values ​​between two basic data units. These values ​​are usually obtained through calculation and used for drawing charts.

[0063] Arithmetic calculation: Calculate the value of an arithmetic progression based on the previous and next real data. The goal is to connect the two basic data units with a line segment.

[0064] In a first aspect of an embodiment of the present application, a method for generating chart data is provided, comprising:

[0065] Obtaining a feature value sequence and partition features of a chart to be generated, wherein the partition features include a preset compression ratio of each partition of the chart to be generated, and the feature value sequence includes multiple subsequences, wherein the multiple partitions correspond to the multiple subsequences in a one-to-one correspondence;

[0066] For any partition, according to a preset compression ratio of the partition, determine the number of values ​​to be filled between every two adjacent characteristic values ​​of the partition to obtain a first number, and determine the first number of values ​​to be filled between every two adjacent characteristic values ​​of the partition;

[0067] Target chart data corresponding to the characteristic value sequence is obtained according to the subsequence corresponding to each partition and the first number of values ​​between every two characteristic values ​​in each partition that needs to be filled with a value.

[0068] It can be seen that through the method of the embodiment of the present application, the target chart data corresponding to the characteristic value sequence can be determined based on the characteristic value sequence and partition characteristics of the chart to be generated, and based on the subsequence corresponding to each partition and the first number of values ​​between each two characteristic values ​​in each partition that needs to be filled with values, thereby obtaining data corresponding to charts with different compression ratios for each partition by filling values ​​between each two characteristic values, thereby improving the visibility of the data change trend when displaying the data of each partition subsequently, and solving the problem in the prior art that when generating charts, it is inconvenient for users to view the data change trend because some position coordinate points are too dense.

[0069] For details, see Figure 1 , Figure 1 A flowchart of a method for generating chart data provided in an embodiment of the present application includes:

[0070] Step S11: Obtain the characteristic numerical sequence and partition characteristics of the chart to be generated.

[0071] The partition characteristics include a preset compression ratio for each partition of the chart to be generated, and the characteristic numerical sequence includes multiple subsequences, wherein the multiple partitions correspond to the multiple subsequences one-to-one. The preset compression ratio for each partition and the characteristic numerical sequence in the embodiment of the present application can be input by the user. For example, when generating a chart, the user inputs the characteristic numerical sequence and the preset compression ratio for each partition through the user interface. The chart to be generated in the embodiment of the present application can be a line chart, a curve chart, etc.

[0072] Among them, the multiple subsequences corresponding to the multiple partitions can be input by the user. In one embodiment, the partition feature also includes the partition ratio between the partitions. The multiple subsequences corresponding to the multiple partitions can also be multiple subsequences obtained by dividing the feature value sequence according to the partition ratio. Among them, the partition ratio can represent the ratio of the number of feature values ​​in the subsequences of each partition. Therefore, the number of feature values ​​in the subsequence corresponding to each partition can be calculated based on the partition ratio and the total number of feature values ​​in the feature value sequence, so that the feature value sequence is divided to obtain multiple subsequences. In the embodiment of the present application, the number of feature values ​​of each partition can be different, or the number of values ​​of some partitions can be the same and the number of values ​​of some partitions can be different. For example, when the feature value sequence is 12, -1, 51, -9, 35, 15, 39, 57, 1, 15, a total of 10 data, and the partition ratio is 5:3:2. The characteristic value sequence can be divided into three parts, and the corresponding number of characteristic values ​​are 5, 3, and 2 respectively. Then the subsequence is divided, and the subsequences corresponding to the three partitions are 12, -1, 51, -9, 35; 15, 39, 57; 1, 15 respectively.

[0073] The method of the embodiment of the present application is applied to a smart terminal and can be implemented through the smart terminal. Specifically, the smart terminal can be a computer, a mobile phone, or a server.

[0074] Step S12: for any partition, determine the number of values ​​to be filled between every two adjacent feature values ​​of the partition according to the preset compression ratio of the partition, obtain a first number, and determine the first number of values ​​to be filled between every two adjacent feature values ​​of the partition.

[0075] Among them, the first number is negatively correlated with the preset compression ratio, and the preset compression ratios of different partitions may be different. Since the preset compression ratio indicates the degree of compression, the preset compression ratio in the embodiment of the present application can be used to represent the data basic unit / X-axis basic unit. For example, 6 X-axis basic units are used to display one data basic unit, and the compression ratio is 1 / 6. Therefore, for any partition, according to the preset compression ratio of the partition, the number of values ​​to be filled between every two adjacent characteristic values ​​of the partition is calculated, and the reciprocal of the compression ratio corresponding to the partition can be calculated, and then the calculated reciprocal is subtracted by 1 to obtain the number of values ​​to be filled between every two adjacent characteristic values ​​of the partition, and the first number and the first number of values ​​are obtained. For example, for the third interval in the above example, the subsequence of the interval is 1,15. When the preset compression ratio corresponding to the partition is 1 / 6, the corresponding reciprocal is calculated to be 6, and then subtracted by 1 to obtain the number of values ​​to be filled between every two adjacent characteristic values ​​of the partition, that is, the first number is 5. Then, the first number of values ​​to be filled between every two adjacent feature values ​​of the partition can be determined in any manner. Optionally, the first number of values ​​needs to be between the values ​​of the two adjacent feature values. For the third interval in the above example, any five values ​​between 1 and 15 can be selected as the values ​​to be filled. Optionally, the first number of values ​​to be filled can be arranged in increasing or decreasing order. In this way, the filled values ​​can more friendly represent the changing trend of the two adjacent feature values.

[0076] Optionally, determining the first number of values ​​to be filled between every two adjacent characteristic values ​​of the partition includes: calculating the arithmetic difference values ​​of the first number between every two adjacent characteristic values ​​of the partition according to the first number of the partition. Specifically, for any partition, according to the first number of the partition, the arithmetic difference values ​​of the first number between every two adjacent characteristic values ​​of the partition are calculated, the difference between every two adjacent characteristic values ​​of the partition can be calculated, and then the arithmetic difference calculation is performed according to the first number of the partition to obtain the arithmetic difference values ​​of the first number between every two adjacent characteristic values. For example, when the first number corresponding to a certain partition is 6, the arithmetic difference values ​​between the two adjacent characteristic values ​​1 and 15 are calculated, the difference between 1 and 15 can be calculated to obtain 14, and then the arithmetic difference calculation is performed according to 14. Since 6 arithmetic difference values ​​need to be calculated, 14 can be divided into 7 equal parts to obtain a tolerance of 2. Therefore, the arithmetic difference values ​​of the first number between 1 and 15 are 3, 5, 7, 9, 11, and 13 respectively. During actual use, for any partition, the number of values ​​to be filled between every two adjacent characteristic values ​​of the partition is calculated according to the preset compression ratio of the partition. Before obtaining the first number, the preset compression ratio can be judged first. When the preset compression ratio of a partition is 1, there is no need to calculate the arithmetic difference value. Since when the preset compression ratio of a partition is 1, the first number of the partition is 0, it is meaningless to calculate the arithmetic difference value.

[0077] Step S13 : obtaining target chart data corresponding to the characteristic value sequence according to the subsequence corresponding to each partition and the first number of values ​​between every two characteristic values ​​in each partition that needs to be filled with a value.

[0078] In one embodiment, target chart data corresponding to the feature value sequence is obtained based on the subsequence corresponding to each partition and the first number of values ​​between every two feature values ​​in each partition that needs to be filled with values. After calculating the first number of arithmetic difference values ​​between every two adjacent feature values ​​of the partition, a partition chart corresponding to each partition is generated based on the subsequence corresponding to each partition and the first number of arithmetic difference values ​​between every two feature values ​​of each partition. The subsequence corresponding to each partition and the first number of arithmetic difference values ​​between every two feature values ​​of each partition can be used as the vertical coordinates, and the subsequence corresponding to each partition or the first number of arithmetic difference values ​​between every two feature values ​​of each partition can be selected in turn as the vertical coordinates of the coordinate points, and a value can be selected as the horizontal coordinate of the coordinate point at intervals of a preset length to generate the chart. For example, for a certain interval, the corresponding subsequence is 1,15, and the first number of arithmetic progression values ​​corresponding to the interval are 3, 5, 7, 9, 11, and 13, respectively. Then, if the horizontal coordinate starts from 1 and generates coordinate points, they can be (1,1), (2,3), (3,5), (4,7), (5,9), (6,11), (7,13), and (8,15), respectively. Thus, a chart corresponding to the partition is generated based on the obtained coordinate points. The generated target icon can be a line chart, and the inflection points in the line chart can be the values ​​in the characteristic value sequence. As the first number of values ​​between each two characteristic values ​​are virtual values, they are not the values ​​in the actual characteristic value sequence and can be omitted from display. Only the actual data can be displayed.

[0079] In one embodiment, according to the subsequence corresponding to each partition and the first number of values ​​between every two feature values ​​in each partition that needs to be filled with values, obtaining the target chart data corresponding to the feature value sequence includes: rendering the partition chart of each partition according to the subsequence corresponding to each partition and the first number of values ​​between every two feature values ​​in each partition that needs to be filled with values, to obtain the target chart corresponding to the feature value sequence. Preferably, the target chart can be a target line chart. In actual use, the partition chart of each partition can be generated first, and then the target chart corresponding to the feature value sequence can be obtained by splicing the partition charts of each partition. Alternatively, the target chart data corresponding to the feature value sequence can be directly rendered according to the subsequence corresponding to each partition and the first number of values ​​between every two feature values ​​in each partition that needs to be filled with values, without first generating the partition chart. Moreover, the charts corresponding to different partitions can be identified by different identifiers in the target chart data.

[0080] In one embodiment, the first number of values ​​to be filled between every two adjacent characteristic values ​​of any partition is determined by calculating the first number of arithmetic differences between every two adjacent characteristic values ​​of the partition based on the first number of the partition. At the same time, when rendering the target chart data, the target line graph corresponding to the characteristic value sequence is rendered. In this way, the first number of values ​​to be filled, i.e., the virtual data, are all on the line segments of the target line graph, and the characteristic values, i.e., the real data, are all on the inflection points of the line graph. The situation of the real data can be intuitively seen through the inflection points, and the changes in the adjacent characteristic values ​​can be observably seen with the help of the first number of virtual values ​​between every two adjacent characteristic values, thereby improving the observability of viewing the changing trend of the data.

[0081] Through the method of the embodiment of the present application, different partitions can be divided according to different partition ratios and preset compression ratios to obtain data corresponding to charts with different compression ratios for each partition, and then generate charts, thereby facilitating the user to view the changing trends of characteristic values. For example, when there is a real-time electrocardiogram, in order to be able to display longer-term heartbeat data, the latest heartbeat data is obviously relatively more important. The solution of the present application can be used to set a low compression ratio for early values ​​and a high compression ratio for new values, thereby facilitating user viewing.

[0082] It can be seen that through the method of the embodiment of the present application, the characteristic numerical sequence and partition characteristics of the chart to be generated can be determined and the target chart data corresponding to the characteristic numerical sequence can be obtained based on the subsequence corresponding to each partition and the first number of values ​​between each two characteristic numerical values ​​in each partition that needs to be filled with numerical values. By filling in numerical values ​​between each two characteristic numerical values, charts with different compression ratios for each partition are generated, which solves the problem in the prior art that when generating charts, it is inconvenient for users to view the changing trend of data because some position coordinate points are too dense.

[0083] Optionally, the partition feature also includes a partition ratio between the partitions, where the partition ratio represents the ratio of the number of feature values ​​of each partition. The multiple subsequences are: multiple subsequences obtained by dividing the feature value sequence according to the partition ratio and the total number of feature values ​​in the feature value sequence.

[0084] The partition ratio represents the ratio of the number of feature values ​​in each partition. Therefore, the total ratio of the number of feature values ​​to be divided in each partition to the total number of feature values ​​in the feature value sequence can be calculated based on the ratio of the number of feature values ​​in each partition. For example, when the ratio of the number of feature values ​​in each partition is 5:3:2, the total ratios of the number of feature values ​​to be divided in each partition to the total number of feature values ​​in the feature value sequence are calculated to be 1 / 2, 3 / 10, and 1 / 5, respectively.

[0085] According to the partition ratio and the total number of characteristic values ​​in the characteristic value sequence, the characteristic value sequence is divided into multiple subsequences. The number of characteristic values ​​corresponding to each partition can be calculated based on the total number of characteristic values ​​in the characteristic value sequence and the total ratio corresponding to each partition. Specifically, the product of the total number of characteristic values ​​in the characteristic value sequence and the total ratio corresponding to each partition can be calculated. For example, when the total number of characteristic values ​​in the characteristic value sequence is 10, when the total ratio of the number of characteristic values ​​to be divided in each partition to the total number of characteristic values ​​in the characteristic value sequence is 1 / 2, 3 / 10, and 1 / 5 respectively, the number of characteristic values ​​corresponding to each partition can be calculated to be 5, 3, and 2. For example, when the characteristic value sequence is 12, -1, 51, -9, 35, 15, 39, 57, 1, 15, a total of 10 data, and the partition ratio is 5:3:2. The feature value sequence can be divided into three parts, with the corresponding number of feature values ​​being 5, 3, and 2, respectively. Then, the subsequences corresponding to the three partitions are divided into 12, -1, 51, -9, 35; 15, 39, 57; and 1, 15. In actual use, if a feature value in the feature value sequence cannot be divided evenly according to the partition ratio, the user can be prompted to modify or select, for example, to select which partition the feature value that cannot be divided evenly should be assigned to.

[0086] It can be seen that through the method of the embodiment of the present application, the feature value sequence can be divided into multiple subsequences in sequence according to the ratio of the number of feature values ​​of each partition, thereby facilitating the generation of a chart for the corresponding partition according to the corresponding subsequence.

[0087] Optional, see Figure 2 Step S13 obtains target chart data corresponding to the feature value sequence based on the subsequence corresponding to each partition and the first number of values ​​between every two feature values ​​in each partition that needs to be filled with a value, including:

[0088] Step S131, determining a plurality of coordinate points corresponding to each partition, wherein the vertical coordinates of the plurality of coordinate points include the values ​​of the subsequence corresponding to each partition and the first number of values ​​between every two characteristic values ​​in each partition that needs to be filled with a value, and the horizontal coordinates of the plurality of coordinate points are spaced uniformly;

[0089] Step S132 : Rendering the partition chart of each partition according to the multiple coordinate points corresponding to each partition to obtain a target chart corresponding to the characteristic value sequence.

[0090] Select a value as the ordinate from the subsequence corresponding to each partition or the first number of arithmetic progressions between every two characteristic values ​​in each partition. The calculated first number of arithmetic progressions can be treated as the value between two adjacent characteristic values ​​and then selected. For example, if the subsequence corresponding to a certain interval is 1, 15, and the first number of values ​​corresponding to the interval are 3, 5, 7, 9, 11, and 13, respectively, then a value can be selected from 1, 3, 5, 7, 9, 11, 13, and 15 as the ordinate. On the horizontal axis, a value is selected as the horizontal coordinate for each interval of a preset length. The horizontal coordinate can be selected based on the last horizontal coordinate in the coordinate points of the previous interval. For example, if the last coordinate point in the coordinate points corresponding to the previous interval is (10, 3), then when selecting the horizontal coordinate, it can be selected after 10, such as 11, 12, 13, 14, 15, 16, 17, 18, and the multiple coordinate points corresponding to the partition are (11, 1), (12, 3), (13, 5), (14, 7), (15, 9), (16, 11), (17, 13), (18, 15). Then, based on the corresponding multiple coordinate points, a partition chart corresponding to the partition is generated. The partition charts of each partition are rendered. The partition charts can be spliced ​​according to the order in the corresponding feature value sequences of the multiple partitions to obtain the target chart corresponding to the feature value sequence. Alternatively, the entire target chart can be directly rendered according to the multiple coordinate points corresponding to each partition to achieve the rendering of each partition chart.

[0091] It can be seen that through the method of the embodiment of the present application, multiple coordinate points corresponding to each partition can be calculated, the partition chart corresponding to each partition can be rendered, and the target chart corresponding to the characteristic value sequence can be obtained, thereby realizing the generation of charts through different compression ratios.

[0092] Optional, see Figure 3 , the above method further includes:

[0093] Step S31: for any two consecutive partitions, determine a second number of values ​​to be filled between the two consecutive partitions, where the second number is the number of values ​​to be filled between the first characteristic value of the latter partition and the last characteristic value of the former partition, and determine the second number of values ​​to be filled between the two consecutive partitions;

[0094] According to the subsequence corresponding to each partition and the first number of values ​​between every two characteristic values ​​in each partition that needs to be filled with a value, target chart data corresponding to the characteristic value sequence is obtained, including:

[0095] Step S32 , obtaining target chart data corresponding to the characteristic value sequence according to the subsequence corresponding to each partition, the first number of values ​​between every two characteristic values ​​in each partition to be filled with values, and the second number of values ​​to be filled between each two consecutive partitions.

[0096] The observability of the changing trend of the data between any two consecutive partitions can be improved by filling a second number of values ​​between any two consecutive partitions. Optionally, the second number of values ​​to be filled between two consecutive partitions is: the first number corresponding to any of the two consecutive partitions, so that the changing trend of the data between two consecutive partitions can be the same or similar to the changing trend of the data in any of the two partitions, thereby improving the observability of the changing trend of the overall target chart data. Optionally, the second number of values ​​can be between the first feature value of the latter partition in the two consecutive partitions and the last feature value of the previous partition, and the second number of values ​​to be filled can be arranged in ascending or descending order. In this way, the filled values ​​can more friendly represent the changing trend of the two adjacent feature values.

[0097] In one embodiment, determining the second number of values ​​to be filled between the two consecutive partitions includes: calculating the second number of arithmetic difference values ​​between the first characteristic value of the latter partition and the last characteristic value of the previous partition in the two consecutive partitions according to the second number corresponding to the two consecutive partitions. In this way, the filled values ​​can more friendly represent the changing trend of the two adjacent characteristic values. In one embodiment, the target chart data obtained can be a target line chart, so that the second number of values ​​to be filled, that is, the virtual data, are all on the line segment of the target line chart, and the characteristic values, that is, the real data, are all on the inflection point of the line chart. The situation of the real data can be intuitively seen through the inflection point, and the change of the characteristic values ​​of the adjacent partitions can be observable with the help of the second number of virtual values ​​between each two adjacent partitions, thereby improving the observability of viewing the changing trend of the data.

[0098] Optionally, the second number of values ​​to be filled between two consecutive partitions is: the first number corresponding to the latter partition of the two consecutive partitions.

[0099] For any two consecutive partitions, the second number of values ​​to be filled between the two consecutive partitions can be the same as the number of values ​​to be filled between every two adjacent characteristic values ​​in the previous partition or the next partition in the two consecutive partitions, that is, the first number. For example, the subsequences corresponding to the three partitions are 12, -1, 51, -9, 35; 15, 39, 57; 1, 15, among which the first partition of the three partitions is 12, -1, 51, -9, 35. For this partition, it is only necessary to perform an arithmetic difference calculation for every two adjacent characteristic values ​​of the partition according to the first number of the partition. For the second partition 15, 39, 57, it is necessary not only to calculate the arithmetic difference calculation for every two adjacent characteristic values ​​in 15, 39, 57, but also to calculate the first number of arithmetic difference values ​​between the last characteristic value 35 of the previous partition and the first characteristic value 15 of the partition, that is, the values ​​to be filled between the first partition and the second partition. Among them, by calculating the second number of arithmetic difference values ​​between the first characteristic value of the latter partition in the two consecutive partitions and the last characteristic value in the previous partition, and finally generating chart data through the arithmetic difference values, not only can the calculation be facilitated and the calculation efficiency be improved, but also when the chart data in the embodiment of the present application is a line graph, the second number of arithmetic difference values ​​can be not displayed, which facilitates the generation of the line graph. In one embodiment, according to the subsequence corresponding to each partition, the first number of values ​​between each two characteristic values ​​in each partition that needs to be filled with values, and the second number of values ​​to be filled between each two consecutive partitions, the target chart data corresponding to the characteristic value sequence is obtained, including:

[0100] Determine multiple coordinate points corresponding to each partition, wherein the vertical coordinates of the multiple coordinate points corresponding to each partition include the values ​​of the first number of values ​​between each two characteristic values ​​in the subsequence corresponding to each partition and each partition that needs to be filled with a value; determine multiple coordinate points corresponding between each two consecutive partitions, wherein the vertical coordinates of the multiple coordinate points corresponding between each two consecutive partitions include the values ​​of the second number of values ​​to be filled between each two consecutive partitions; the horizontal coordinate intervals of the multiple coordinate points corresponding to each partition and the multiple coordinate points corresponding between each two consecutive partitions are the same;

[0101] According to the multiple coordinate points corresponding to each partition and the multiple coordinate points corresponding between two consecutive partitions, the partition chart of each partition and the part between two consecutive partitions are rendered to obtain a target chart corresponding to the feature value sequence.

[0102] The target chart can be obtained by rendering each partition icon and the part between each partition separately, and then splicing each part. Alternatively, the target chart can be directly rendered according to the coordinate points to achieve the rendering of each partition chart and the part between each partition.

[0103] In order to illustrate the method of the embodiment of the present application, the following is described in conjunction with specific embodiments. Figure 4 ,include:

[0104] 1. Get all the data of the chart. For example, get the original data array: 12, -1, 51, -9, 35, 15, 39, 57, -11, 51, a total of 10 data.

[0105] 2. Split the data according to the basic parameters. For example, when the partition ratio is (5:3:2), the original data array can be cut into three segments: 12, -1, 51, -9, 35; 15, 39, 57; -11, 51.

[0106] 3. Calculate virtual values ​​based on the compression ratio. For example, the first segment has a compression ratio of 1, so no virtual values ​​need to be filled in. The second segment has a compression ratio of 1 / 3, which means that three X-axis basic units represent one data basic unit, and two virtual values ​​need to be filled in. For example, two values ​​need to be filled in between 15 and 39, namely 23 and 31, and the final result is an arithmetic progression of 15, 23, 31, and 39.

[0107] 4. Connect all the data to get the rendering data. For example, the final data after filling is: 12,-1,51,-9,35,28.33,21.67,15,23,31,39,45,51,57,45.67,34.33,23,11.67,0.33,-11,-0.67,9.67,20,30.33,40.67,51.

[0108] 5. Import the data into the component to render the chart. For example, you can mark each segment of chart data separately, and use different marks to identify different segments.

[0124] The chart rendering submodule is used to render the partition chart of each partition according to the multiple coordinate points corresponding to each partition, and obtain the target chart corresponding to the characteristic value sequence.

By filling values ​​between each two characteristic values, data corresponding to charts with different compression ratios for each partition can be obtained, so that the visibility of the data change trend can be improved when the data of each partition is subsequently displayed, and the problem of the existing technology that when generating charts, some position coordinate points are too dense, which makes it inconvenient for users to view the data change trend.
