[0049] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0050] In the embodiments of the present application, words such as "first" and "second" are used to distinguish the same or similar items with substantially the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit the difference.

[0051] It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way. In the embodiments of the present application, "at least one" refers to one or more, and "more than one" refers to two or more.

[0052] It should be noted that the “at…” in the embodiments of the present application may be the instant when a certain situation occurs, or may be a period of time after the occurrence of a certain situation, and the embodiments of the present application do not specifically limit this.

[0053] In the embodiments of the present application, the following terms may appear, and their corresponding explanations are as follows:

[0054] Interval bar chart: A bar chart that displays interval ranges, usually used to show the distribution of values ​​or the range of categorical data.

[0055] Coordinate system: used to define how data is positioned in a chart. Common ones include rectangular coordinate system and polar coordinate system.

[0056] Chart configuration items: parameters used to define the visual properties and interactive behaviors of a chart.

[0057] Hover: An interactive event in the browser. When the mouse pointer hovers over a specified element, this event can trigger a change in the style of the mouse pointer or a change in the style of the specified element.

[0058] AntV: An open source data visualization solution.

[0059] ECharts: An open source data visualization solution.

[0060] In some related technologies, some open source visualization solutions, such as AntV or ECharts, can complete commonly used graphical representations, such as interval bar charts.

[0061] Figure 1 An open source visualization solution is shown to implement an interval bar chart. Figure 1 As shown, the interval bar chart is implemented based on a plane rectangular coordinate system, wherein the plane rectangular coordinate system consists of an X-axis and a Y-axis that are perpendicular to each other and have a common origin, the X-axis is located in a horizontal position, and each unit length of the X-axis represents a different mouth (month), and the Y-axis is located in a vertical position, and each unit length represents a different number.

[0062] like Figure 1 As shown in the figure, the bar chart is displayed vertically on the X-axis, and the bottom edge of the bar may not be aligned with the X-axis. By configuring the hover function for the bar, the floating prompt function is realized, that is, the mouse pointer hovers over the bar to trigger the information prompt corresponding to the bar. You can also configure the legend of the interval bar chart, such as Figure 1 The "Interval Bar Chart" in the figure is the configuration legend.

[0063] However, the interval bar chart of the open source visualization solution can only be configured with one bar on one X-axis, such as Figure 1 As shown, the elements Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec, and Total on the X-axis correspond to only one bar, and if you want to configure colors for different bars, the open source visualization solution can only configure a single bar, but cannot configure different colors for different bars on the same axis.

[0064] In order to solve the above technical problems, the embodiments of the present application provide a data visualization method and device, an electronic device, and a computer-readable storage medium. The same visualization identifier can form different visualization parameter groups with different visualization intervals. When drawing different visualization parameter groups corresponding to the same visualization identifier, it is possible to configure multiple bars on the same coordinate axis.

[0065] The data visualization method provided by the exemplary embodiment of the present application is described below with reference to the accompanying drawings. It should be noted that the above application scenarios are only shown to facilitate understanding of the spirit and principles of the present application, and the implementation of the present application is not limited in this regard.

[0066] Figure 2 A schematic diagram of a data visualization method provided in an embodiment of the present application, the specific implementation process of the method may include the following steps:

[0067] S210: Acquire at least one visualization parameter group;

[0068] The visualization parameter group may include a visualization identifier and a visualization interval; the visualization interval may be a data interval, which includes an interval upper bound and an interval lower bound.

[0069] The visualization parameter group may be generated according to the visualization data. The visualization data may be the recorded data of the object to be recorded. The visualization identifier in the visualization parameter group may be the identifier of the object to be recorded, and the visualization interval may be the data interval corresponding to the recorded data.

[0070] Multiple visualization parameter groups can be obtained according to the visualization data.

[0071] S220: drawing a visualization bar corresponding to the visualization parameter group in a preset coordinate system according to the visualization parameter group; the position of the visualization bar in the coordinate system is determined according to the visualization identifier, and the length of the visualization bar is determined according to the visualization interval;

[0072] The preset coordinate system may be a rectangular coordinate system.

[0073] Determining the position of the visualization bar in the coordinate system according to the visualization identifier may be determining the coordinates of an axis corresponding to the visualization bar according to the visualization.

[0074] Determining the length of the visualization bar according to the visualization interval may be determining the coordinates of another axis of the visualization bar according to the upper bound and the lower bound of the visualization interval.

[0075] Draw visualization bars in a rectangular coordinate system according to the determined coordinates.

[0076] The data visualization method provided by the exemplary embodiment of the present application is described in detail below.

[0077] As described above, the visualization parameter set may be generated based on the visualization data.

[0078] Figure 3 A schematic diagram of a process for obtaining visualization data and generating visualization parameters according to the visualization data is shown. Figure 3As shown, obtaining visualization data and generating visualization parameters according to the visualization data may include the following steps:

[0079] S310: Recording the state of the object to be recorded within a preset time period;

[0080] The object to be recorded may be a means of transport, including a car, a ship, a train, etc. The preset time period may be a day or a daytime period.

[0081] Recording the state of the object to be recorded may include recording the state of the object to be recorded at the start time of a preset time period, and when the state of the object to be recorded changes, recording the changed state of the object to be recorded, and recording the state of the object to be recorded at the end time of the preset time period.

[0082] S320: Determine, according to the state of the object to be recorded, at least one time interval during which the state of the object to be recorded does not change;

[0083] Determining at least one time interval during which the state of the object to be recorded does not change according to the state of the object to be recorded may be determining a time interval during which the state of the object to be recorded does not change according to a start time point of a preset time period and a time point when the state of the object to be recorded changes for the first time.

[0084] A time interval in which the state of an object to be recorded does not change may be determined according to a time point at which the state of an adjacent object to be recorded changes.

[0085] A time interval in which the state of the object to be recorded does not change can be determined according to the time point when the state of the object to be recorded last changed and the end time point of the set time period.

[0086] S330: Determine a visualization identifier according to the object to be recorded, and determine a visualization interval according to the time interval;

[0087] Determining the visualization identifier according to the object to be recorded and determining the visualization interval according to the time interval may be taking the identifier of the object to be recorded as the visualization identifier and determining the time interval as the visualization interval.

[0088] The visualization identifier and a visualization interval are combined into a visualization parameter group. When multiple visualization intervals are obtained, the visualization identifier and the multiple visualization intervals are combined into multiple visualization parameter groups. The multiple visualization parameter groups are all drawn using the visualization method of the embodiment of the present application.

[0089] Since a visualization interval is a time interval in which the state of the object to be recorded does not change, the visualization bar corresponding to the visualization parameter group composed of the visualization interval is a visualization of a state of the object to be recorded, and different visualization bars are visualizations of different states of the object to be recorded.

[0090] That is to say, using the visualization method of the embodiment of the present application, the state change of the object to be recorded can be represented in the form of a bar.

[0091] As described above, the preset coordinate system may be a rectangular coordinate system, and the position of the visualization bar in the coordinate system may be determined according to the visualization mark, and the length of the visualization bar may be determined according to the visualization interval to draw the visualization bar.

[0092] Figure 4 A schematic diagram of a process for drawing a visualization bar in a rectangular coordinate system is shown, Figure 4 As shown, drawing a visualization bar in a rectangular coordinate system may include the following steps:

[0093] S410: Determine the starting Y-axis coordinate and the ending Y-axis coordinate of the visualization bar in the rectangular coordinate system according to the visualization identifier;

[0094] The Y-axis of the rectangular coordinate system is configured with a visual identifier, that is, different visual identifiers correspond to different Y-axis coordinates.

[0095] Since the Y-axis is configured with a visualization symbol, different visualization symbols can be used at different positions on the Y-axis. The visualization bar has width and length. Points cannot be used to represent visualization expressions, but line segments are needed to represent visualization symbols. Therefore, each segment of the Y-axis with a length of N can represent a visualization symbol.

[0096] Determining the starting Y-axis coordinate and the ending Y-axis coordinate of the visualization bar in the rectangular coordinate system according to the visualization identifier can be performed by obtaining the corresponding equal division on the Y-axis according to the visualization identifier, using the starting position of the equal division as the starting Y-axis coordinate and the ending position of the equal division as the ending Y-axis coordinate.

[0097] S420: determining a starting X-axis coordinate of the visualization bar in the rectangular coordinate system according to an upper boundary of the visualization interval, and determining a terminating X-axis coordinate of the visualization bar in the rectangular coordinate system according to a lower boundary of the visualization interval;

[0098] Determining the starting X-axis coordinate of the visualization bar in the rectangular coordinate system according to the upper limit of the visualization interval, and determining the ending X-axis coordinate of the visualization bar in the rectangular coordinate system according to the lower limit of the visualization interval can be determining the corresponding coordinate on the X-axis according to the value of the upper limit of the visualization interval, that is, the starting X-axis coordinate, and determining the corresponding coordinate on the X-axis according to the value of the lower limit of the visualization interval, that is, the ending X-axis coordinate.

[0099] S430: Determine vertex coordinates of multiple vertices of the visualization bar according to the starting Y-axis coordinate, the ending Y-axis coordinate, the starting X-axis coordinate, and the ending Y-axis coordinate;

[0100] The vertex coordinates of the multiple vertices of the visualized bar are (starting X-axis coordinate, starting Y-axis coordinate), (starting X-axis coordinate, ending Y-axis coordinate), (ending X-axis coordinate, starting Y-axis coordinate), and (ending X-axis coordinate, ending Y-axis coordinate).

[0101] S440: Draw a visualization bar in a rectangular coordinate system according to the vertex coordinates, and place the visualization bar horizontally in the rectangular coordinate system;

[0102] Since the Y-axis is configured with a visualization mark, each segment of the Y-axis with a length of N represents a visualization mark. Therefore, the width of all visualization bars is consistent, and the length is determined according to the visualization interval. The lengths of different visualization bars are inconsistent. Therefore, the visualization bars are placed horizontally in the rectangular coordinate system.

[0103] The vertex coordinates determined in S430 are used as vertices of the visualization bar to draw a rectangle, that is, the visualization bar.

[0104] You can also use the rectangular coordinate system's X-axis to configure the visualization mark and the Y-axis to configure the visualization interval. Figure 4 In the corresponding embodiment, the X-axis and the Y-axis are swapped, and a similar method can be used to draw a visualization bar, which will not be repeated here.

[0105] In some possible implementations, the visualization parameter group further includes a visualization mode. The visualization mode is a mode of drawing a visualization bar in a preset coordinate system. Different visualization modes correspond to different visualization elements. When drawing a visualization bar, the visualization element corresponding to the visualization mode is used for drawing.

[0106] Visual elements can include colors and can also include bar shapes, such as rounded rectangles and normal rectangles.

[0107] That is to say, if the visualization element corresponding to the visualization mode of the visualization parameter group is yellow and rounded rectangle, when drawing the visualization bar in step S440, the vertex coordinates are used as the vertices of the visualization bar to draw the rounded rectangle and fill the rounded rectangle with yellow.

[0108] The visualization method can be determined according to the state of the object to be recorded within the time interval. Different states of the object to be recorded correspond to different visualization elements, so that the state of the object to be recorded can be determined by the color and shape of the visualization bar.

[0109] In some possible implementations, the drawing process may be implemented based on an open source visualization solution, such as AntV or ECharts. Specifically, the above process may be implemented based on a public function of the open source visualization solution.

[0110] If you want to draw visualization bars corresponding to multiple visualization parameter groups, since the logic of drawing the visualization bars corresponding to each visualization parameter group is consistent, you can draw the visualization bars corresponding to multiple visualization parameter groups through a loop.

[0111] That is, after drawing the visualization bar corresponding to one visualization parameter group, continue to draw the visualization bar corresponding to the next visualization parameter group, until the visualization bars corresponding to all visualization parameter groups are drawn, and then exit the loop.

[0112] In some possible implementations, in order to prevent multiple entries into the loop and thus waste computing resources, a switch value may be set and initialized to a value that meets a preset loop start condition. When the switch value meets the preset loop start condition, a loop is entered that uses an open source visualization solution to draw visualization bars corresponding to the visualization parameter group in a preset coordinate system according to the visualization parameters. When exiting the loop, the switch value is modified so that it does not meet the preset loop start condition to avoid entering the loop a second time.

[0113] The following specific example specifically introduces the data visualization method provided in the embodiment of the present application.

[0114] Specifically, the embodiments of the present application can be used in scenarios such as automobile charging, scheduling, mileage recording, etc., and can also be applied to other transportation industries such as ships, airplanes, trains, etc. that involve visualization of interval-type data.

[0115] Taking the bus status record as an example, convert the time of a day into a total of minutes, and record the minutes corresponding to the time points when the bus status changes during the day (conversion into minutes is to avoid the influence of different time expressions such as 12-hour system or 24-hour system on the time axis, that is, the form of the X-axis).

[0116] Among them, the states of the public bus include up, down, and other states (such as charging). The minutes corresponding to the time points when adjacent states change are used as the upper and lower bounds of a time interval. The bus logo is determined as a visualization logo, the time interval is determined as a visualization interval, and the state of the bus in the time interval is determined as a visualization method, generating multiple visualization parameter groups.

[0117] Specifically, the generated visualization parameter group can be in the form of an object array, and its content can include type, values, and way, where type is a visualization identifier, and its value can be the number of the bus. Value is interval data, which is the visualization interval obtained above, and way is a visualization method. Its value can be E, which means that the bus status is up, and the corresponding visualization element is green and a rounded rectangle with rounded corners at the upper left and lower left corners. Its value can also be S, which means that the bus status is down, and the corresponding visualization element is blue and a rounded rectangle with rounded corners at the upper right and lower right corners. Its value can also be M, which means that the bus status is charging, and the corresponding visualization element is red and a standard rectangle. For example, a visualization parameter group can be {type:18,values:[280,432],way:E}, which means that the bus with the identifier 18 is in the up state during the time period from 280 minutes to 432 minutes.

[0118] Use the Bar method in @antv / g2plot to draw a rectangular coordinate system. The X-axis of the rectangular coordinate system is the time axis. The time axis uses a 24-hour system and is drawn in minutes.

[0119] According to the visualization mark, the corresponding equal division on the Y axis is obtained, and the starting position of the equal division is used as the starting Y axis coordinate, and the ending position of the equal division is used as the ending Y axis coordinate. According to the value of the upper limit of the visualization interval, the corresponding coordinate on the X axis is determined, that is, the starting X axis coordinate, and according to the value of the lower limit of the visualization interval, the corresponding coordinate on the X axis is determined, that is, the ending X axis coordinate. The vertex coordinates of the multiple vertices of the visualization bar are respectively (starting X axis coordinate, starting Y axis coordinate), (starting X axis coordinate, ending Y axis coordinate), (ending X axis coordinate, starting Y axis coordinate), (ending X axis coordinate, ending Y axis coordinate), and a rectangle is drawn in the rectangular coordinate system with the vertices corresponding to the vertex coordinates placed horizontally in the rectangular coordinate system.

[0120] For example, the bar corresponding to {type:18,values:[280,432],way:E} is a rounded rectangle with 18 on the Y axis, 4:40-7:12 on the X axis, and blue color, and the upper right and lower right corners are rounded.

[0121] When using the Bar method in @antv / g2plot for drawing, some configurations need to be modified. The half-angle and rounded corners are configured through the barStyle configuration. This configuration receives an object, in which the radius is the configuration of the half-angle or rounded corner. A bar has four corners in total. The returned radius is an array that can receive four values, such as [10,10,0,0], which means the rounded corners on the left (upper left and lower left). The way in the above data can be used to determine the direction of the vehicle's movement, whether it is up, down, or charging. Charging does not require rounded corners. This configuration is a loop. Because each piece of data needs to be processed, a switch count is required to determine whether to enter the loop, otherwise the loop will enter twice, which will affect performance. The method for configuring half-angle rounded corners is as follows:

[0122] barStyle:(()=>{

[0123] var count = 0

[0124] var arr = []

[0125] return(arg)=>{

[0126] const{type=""}=arg

[0127] if(type===”){

[0128] count=count+1

[0129] }

[0130] / / Solve the problem of loop entering twice

[0131] if(count!==1)return

[0132] arr.push(type)

[0133] const currentArr=data.filter((item)=>item.type===type)

[0134] const filterArr=arr.filter((item)=>item===type)

[0135] / / Get the current round trip type

[0136] const wayType=currentArr[filterArr.length-1]? .way

[0137] if (wayType === 'E') {

[0138] return{radius:[10,10,0,0]}

[0139] }else if(wayType===='M'){

[0140] return{radius:[0,0,0,0]}

[0141] }

[0142] return{radius:[0,0,10,10]}

[0143] }

[0144] })(),

[0145] The configuration for color is similar to the rounded corner configuration above, except that we can directly return the color value string here. We can also use the way field to distinguish colors. This method of returning the callback function will also process the loop twice, which can be solved by switching count. The color configuration code is as follows:

[0146] color:(()=>{

[0147] var count = 0

[0148] var arr = []

[0149] return(arg)=>{

[0150] const{type=""}=arg

[0151] if(type===”){

[0152] count=count+1

[0153] }

[0154] / / Solve the problem of loop entering twice

[0155] if(count!==1)return

[0156] arr.push(type)

[0157] const currentArr=data.filter((item)=>item.type===type)

[0158] const filterArr=arr.filter((item)=>item===type)

[0159] / / Get the current round trip type

[0160] const wayType=currentArr[filterArr.length-1]? .way

[0161] if (wayType === 'E') {

[0162] return '#436FF6'

[0163] }else if(wayType===='M'){

[0164] return '#F76560'

[0165] }

[0166] return '#00B589'

[0167] }

[0168] })()

[0169] The final drawn bar can be Figure 5 As shown, Figure 5 The Y-axis of the rectangular coordinate system is the bus number (such as 1, 2, 3, etc.), the X-axis is time (from 4:30 to 24:00), and multiple bars are placed horizontally in the coordinate system. Each row of the Y-axis can be configured with multiple horizontal bars, and the rounded corners or color of the columns can be configured. Each bar in the same row represents the status of the same bus at different times. Therefore, the bars can be used to achieve visual displays such as vehicle scheduling or vehicle charging information.

[0170] At the same time, a hover event can be set for each bar. When the mouse hovers over a bar, the corresponding information of the bar is displayed, such as the vehicle number, itinerary (i.e., bus status), and operating time (i.e., the corresponding time interval). Figure 5 As shown, the corresponding information of the corresponding bar is that the bus with vehicle number 22 is in the up state from 08:46 to 11:24.
