[0065] The chart customization component is used to perform customization operations on the generated water conservancy chart, and display the execution results of the customization operations on the visualization interface display component.

[0066] For the data module, a relational database such as MySQL, PostgreSQL, OracleDatabase, SQLServer, etc. can be used, or a non-relational database such as MongoDB, Cassandra, Redis, Couchbase, etc. can be used. The present invention does not limit the type of database here, as long as the selected database can store water conservancy data.

[0067] Water conservancy data refers to various data related to the management, protection, utilization and planning of water resources. These data types are extensive, including but not limited to the following:

[0068] (1) Infrastructure status monitoring data: This type of data involves real-time status monitoring data of water conservancy infrastructure such as reservoirs, dams, levees, and irrigation systems, including parameters such as water level, flow, seepage, and deformation.

[0076] (9) Some unstructured data, including engineering drawings, construction records, operation management records, expert knowledge, etc.

[0077] After obtaining water conservancy data, preprocessing operations are required, including data cleaning, data conversion, data dimension reduction, data reconstruction, etc. Preprocessing can improve data quality, increase data visualization, and increase data comparability and operability.

[0078] For the chart type setting component in the application module, the display system proposed in the present invention supports a variety of chart types: including bar charts, line charts, cross-sectional charts, radar charts, dashboards, and pie charts, to meet the different visualization needs of users.

[0081] The cross-section diagram includes: river cross-section diagram, water surface line, and cross-section infiltration line. For example, for the cross-section infiltration line diagram, the cross-section infiltration line diagram supports the display of the current water level, seepage water level, infiltration line, and flood season water level. The starting point of the infiltration line is the intersection of the current water level and the dam crest elevation, and the vertices of each seepage water level are connected by a dotted line. The end point is the intersection of the extension line of the seepage water level line and the dam crest elevation. The cross-section infiltration line diagram is as follows: Figure 3 described.

[0083] For the chart property setting component in the application module, it includes X-axis display format setting and Y-axis display format setting.

[0084] The content of the X-axis display format setting includes: time display format, the time display format includes the X-axis minimum scale value and the X-axis maximum scale value, the X-axis minimum scale value and the X-axis maximum scale value are determined based on business needs, and the display format of the X-axis minimum scale value is year-month-day hour-minute-second, year-month-day hour-minute or year-month-day hour.

[0085] Preferably, after determining the display format value of the minimum scale value of the X-axis, the remaining scale values ​​on the X-axis only display the part that is different from the minimum scale value of the X-axis in time format, such as Figure 2 As shown in the figure, the first X-axis scale value is 2023-01-0309, and the second X-axis scale value is only 10 o'clock because the year, month and day are the same as the first X-axis scale value. This simplified method can greatly improve the data display effect, allowing users to more clearly and conveniently obtain the time corresponding to the current X.

[0086] Exemplarily, the coordinate system requirements of the water conservancy chart are that the x-axis is the time axis, the axis label of the time axis can display 0 o'clock or 8 o'clock, and the axis label can be displayed in the format of year-month-day-hour-minute-second or year-month-day-hour-minute or year-month-day-hour.

[0087] In addition, the display format of the X-axis data can also be determined according to the data read from the data module.

[0088] The contents of the Y-axis display format settings include: Y-axis maximum scale value, starting point value, Y-axis starting point limit value, step value, preset minimum step value, and segment value.

[0089] The starting point value supports custom settings of external input, and the default value is 0;

[0090] The Y-axis starting point limit value supports custom settings of external input, and the default value is 0;

[0091] The step value supports custom settings of external input;

[0092] The preset minimum step size supports custom configuration of external input, and the default value is 0;

[0093] The segment value includes a default segment value or a custom configuration input externally, and the default segment value is 6.

[0094] Before creating a water conservancy chart, users can set the display format of the X-axis and Y-axis to meet the customized display requirements of the water conservancy chart.

[0095] For the chart generation component in the application module, a water conservancy chart is generated based on the selected chart type and the set X, Y axis data display format, as well as the water conservancy data read from the data module, and the visual interface display component is used to display the generated water conservancy chart.

[0096] Specifically, after the user selects the required chart type and sets the display format according to business requirements, the chart generation component generates a chart based on business data. The specific steps are as follows:

[0097] A1: Read the business data corresponding to the business requirements from the data module, the business data is (Xi , Y i ), X i is time, Y i For X i The corresponding actual value is i=1, 2, 3, ..., N.

[0098] A2: If each Y in the business data i The actual values ​​of are the same. If they are the same, perform the following steps:

[0099] Determine whether the step value is entered. If it is entered, the input is used as the Y-axis step value. If it is not entered, Step = Y i / The number of digits corresponding to the integer part of 10 is taken as the step value, where Step is the step value;

[0100] Exemplarily, given a set of data sequences (98, 98, 98, 98, 98), then Step=98 / 10=9.8, the number of bits in the integer part of the value 9.8 is 1, so the step value=1.

[0101] Determine whether to enter a starting point value. If a starting point value is entered, the starting point value is used as the initial value of the Y-axis data. If no starting point value is entered, As the initial value of the Y-axis data, and determine whether the FirstPoint is less than the Y-axis starting point limit value, if so, the Y-axis starting point limit value is used as the initial value of the Y-axis data;

[0102] For example, given a set of data sequences (0.5, 0.5, 0.5, 0.5, 0.5), if the configured step parameter or the calculated step parameter is 0.1, the step value is 0.1. According to the starting point calculation formula It can be obtained that (0.5 / 0.1-5 / 2)=2.5≈2(round down)*0.1=0.2, so the final step value is 0.1 and the starting value is 0.2.

[0103] If they are not the same, go to step A3.

[0104] A3: If Y in the business data i If there are different actual values, perform the following steps:

[0105] Determine whether to enter a starting point value. If you enter a starting point value, the input value will be used as the initial value of the Y-axis data; if you do not enter a starting point value, As the initial value of the Y-axis data, and determine the Is it less than the Y-axis starting point limit value? If so, the Y-axis starting point limit value is used as the initial value of the Y-axis data. Min is the X value in the business data. i The minimum value of

[0106] If the difference between adjacent scale values ​​on the Y-axis is limited to 5 or a multiple of 5, the step value is calculated as follows:

[0107]

[0108] Among them, Num is the segment value, Max is the Y in the business data i The maximum value of Step is converted to A*10 n In the numerical form, given the second numerical set {1, 1.5, 2.5, 5, 10}, take the two elements closest to A from the second numerical set as the candidate step values, and bring them into Get NumNew1 and NumNew2, compare |NumNew1-Num| and |NumNew2-Num|, take NumNew corresponding to the minimum value as the optimal number of segments, and find the corresponding optimal step value, determine the size of the optimal step value and the preset minimum step value, if less than, take the preset minimum step value as the optimal step value, and calculate the Y-axis scale value, otherwise, calculate the Y-axis scale value with the optimal number of segments and the optimal step value; if FirstPoint is greater than the Y-axis starting point limit value, the initial value of the Y-axis data is calculated as follows:

[0109] B1: Calculate the minimum outsourcing scale number Calculate the maximum outsourcing scale number Y min is the minimum value of the business data center Yi, Y max is the maximum value of the business data center Yi, To round down, To round up;

[0110] B2: If (minVal+maxVal) / 2<Num / 2, the number of segments needs to be updated. The new number of segments is:

[0111]

[0112] Otherwise, there is no need to update the number of segments;

[0113] B3: Calculate the new starting point value FirstPointNew=FirstPoint-Step*NumNew. If FirstPointNew is greater than the Y-axis starting point limit value, FirstPointNew is used as the initial value of the Y-axis data.

[0114] For example, if the finally calculated A=1.2, the closest elements in the second numerical value set are 1 and 1.5.

[0115] Through the above-mentioned method B1-B3, that is, through the relationship between the coordinate axis range and the numerical range, the problem of the chart distribution being biased upward or downward is solved by increasing or decreasing N steps, so that the final displayed chart is located in the middle position of the coordinate system.

[0116] If the difference between adjacent Y-axis scale values ​​is not limited to 5 or a multiple of 5, the step value is calculated as follows:

[0117] Determine whether a step value is input. If input, use the input as the step value to be selected for the Y-axis. If not input, round up Step = (Max-FirstPoint) / (Num-1) to an element in the third numerical set (2, 4, 5, 8, 10), and use the element as the step value to be selected. Determine the size of the step value to be selected and the preset minimum step value. If it is less than, use the preset minimum step value as the optimal step value and calculate the Y-axis scale value. Otherwise, use the step value to be selected as the optimal step value, and calculate the Y-axis scale value with the optimal number of segments and the optimal step value.

[0118] Exemplarily, when Step=4.5, it is rounded up to element 5 in the third numerical set, and therefore, 5 is used as the step value to be selected; when Step=3.2, it is rounded up to element 4 in the third numerical set, and therefore, 4 is used as the step value to be selected; when Step=6.1, it is rounded up to element 8 in the third numerical set, and therefore, 8 is used as the step value to be selected.

[0119] A4: According to the above (X i , Y i ), the step value, the initial value of the Y-axis data, or according to the (X i , Y i ), the initial value of the Y-axis data, the optimal number of segments and the optimal step value generate a water conservancy chart.

[0120] It is worth mentioning that if the X-axis is not a time axis but a value axis, the method of calculating the starting point value and the step value is the same as that described for the Y-axis, but does not include the case of calculating the starting point and the step value when the difference between adjacent scale values ​​of the Y-axis is limited to 5 or a multiple of 5.

[0121] The chart customization component in the display module is used to customize the generated water conservancy chart and display the execution result of the customization operation on the visual interface display component. The chart customization component includes:

[0122] The default data display subcomponent, after clicking this subcomponent, click any position on the generated water conservancy chart, even if there is no corresponding data in the data module at the current click position, it can still display the X-axis scale value and Y-axis scale value corresponding to the current click position.
