Referring to fig. 2, a schematic flow chart of a data display method provided in the embodiment of the present application is shown. As shown in fig. 2, the method comprises the steps of:

in step 201, in response to an operation of generating map information of a target geographic area triggered by a user, obtaining map data of the target geographic area; and displaying the three-dimensional map of the target geographic area in a display interface based on the map data.

Wherein the target geographic area comprises at least one sub-geographic area.

In one possible embodiment, the map data for the target geographic area is derived by the ecoharts map component using the GeoJson format map data. A map of a certain city, a map of a certain country, a map of the world, and the like may be acquired.

In a possible implementation manner, the displaying of the three-dimensional map of the target geographic area in the display interface based on the map data in the embodiment of the present application may be performed as the steps shown in fig. 3:

in step 301, a plurality of two-dimensional maps corresponding to target geographic areas including the respective sub-geographic areas are generated based on the map data;

in step 302, display information corresponding to each two-dimensional map is determined; and respectively adjusting the display content of each two-dimensional map in the display interface according to the display information corresponding to each two-dimensional map, and generating the three-dimensional map of the target geographic area.

The display information in the embodiment of the present application includes, but is not limited to, a hierarchy, an offset value, an offset angle, a color value, and a size of a shadow.

Illustratively, as shown in fig. 4, a user clicks a data presentation application of a terminal interface to trigger a function of generating map information of a target geographic area, then map data of the target geographic area in a background is obtained, then a plurality of two-dimensional maps corresponding to the target geographic area including each sub-geographic area are generated based on the map data, then the plurality of two-dimensional maps are overlaid together, a level value (Z value) of each two-dimensional map is sequentially reduced, positions of the two-dimensional maps sequentially shift downward and rightward, a background color is added to the uppermost two-dimensional map to show a geological effect, and a shadow color and a shadow size are set for the lowermost two-dimensional map to show a three-dimensional effect, as shown in fig. 5, the three-dimensional map of the target geographic area is shown.

Illustratively, as shown in fig. 6, when a user clicks a map application of a terminal interface, such as a grand map, a Baidu map, etc., clicks a target geographic area (as shown in fig. 7) on the map application interface or clicks a determination button (as shown in fig. 8) after inputting the target geographic area on the map application interface, a function of generating map information of the target geographic area is triggered, map data of the target geographic area in a background is obtained, then, based on the map data, a plurality of two-dimensional maps corresponding to the target geographic area including each sub-geographic area are generated, then, the plurality of two-dimensional maps are overlaid together, a level value (Z value) of each two-dimensional map is sequentially reduced, a position is sequentially shifted downwards and rightwards, a background color is added to the uppermost two-dimensional map to show a geological effect, and a shadow size is set on the lowermost two-dimensional map to make the map show a stereoscopic effect.

In step 202, at least one target data corresponding to each sub-geographic area in the target geographic area is obtained in response to a data display operation triggered by a user in the display interface.

The target data are statistical data of the times of the target events of the corresponding sub-geographic areas within a preset time length.

In a possible implementation manner, the obtaining of at least one target data corresponding to each sub-geographic area in the target geographic area in the embodiment of the present application may be implemented as the steps shown in fig. 9:

in step 901, a plurality of candidate events are presented in a display interface;

in step 902, in response to a user operation of selecting a target event from a plurality of candidate events, determining at least one target event selected by the user;

in step 903, for any one target event, target data of the target event corresponding to each sub-geographic area in the target geographic area is determined.

In specific implementation, the target data of the target event corresponding to each sub-geographic area in the target geographic area can be obtained from the background at regular time in an axios manner. The background data returns data by taking the sub-geographic areas as dimensions, and the data of each sub-geographic area comprises the name (code) of the sub-geographic area and the value of the target data of the target event to be displayed. And then circularly processing the data acquired by the background, and respectively putting the target data of different types into corresponding data arrays, so as to be convenient for generating different histograms subsequently. Wherein a target event comprises at least one category of target data.

Illustratively, as shown in fig. 10, after a user clicks a button of a data presentation operation in a display interface, a plurality of candidate events, including event 1, event 2, \8230;, event n, as shown in fig. 11, are presented in the display interface, and then the user clicks and selects event 1, and target data of event 1 corresponding to each sub-geographic area in the target geographic area is obtained from the background. For example, the event 1 may be a geological disaster event, and target data of the geological disaster event corresponding to each sub-geographic area in the target geographic area is obtained from the background, but the geological disaster event may be classified into various categories such as debris flow, earthquake, flood disaster, and the like, and therefore, the target data of different categories of the geological disaster event obtained from the background may be placed into corresponding data arrays.

In step 203, for any one sub-geographic area, drawing a three-dimensional histogram corresponding to each target data according to at least one target data corresponding to the sub-geographic area; and displaying a three-dimensional stacked histogram obtained by overlapping the three-dimensional histograms corresponding to the target data on the sub-geographic area in the three-dimensional map.

In a possible implementation manner, in the embodiment of the present application, the step of drawing a three-dimensional histogram corresponding to each target data according to at least one target data corresponding to the sub-geographic area may be implemented as shown in fig. 12:

in step 1201, cylinder heights of the target data corresponding to the sub-geographic area are determined based on at least one target data corresponding to the sub-geographic area and a preset cylinder height threshold.

In step 1202, a three-dimensional histogram corresponding to each target data is drawn based on the cylinder height of each target data corresponding to the sub-geographic area.

In a possible implementation manner, in order to avoid that the data amount is large and the height of the histogram is too high when the numerical value is too large, in the embodiment of the present application, the height of the pillar of each target data corresponding to a sub-geographic area is determined based on at least one target data corresponding to the sub-geographic area and a preset pillar height threshold, and the steps shown in fig. 13 may be performed:

in step 1301, determining target data with the maximum data value in the at least one target data based on the at least one target data corresponding to the sub-geographic area;

in step 1302, determining a data value corresponding to a unit cylinder height based on the target data with the largest data value and a preset cylinder height threshold;

in step 1303, the cylinder height of each target data corresponding to the sub-geographic area is determined based on the data value corresponding to the unit cylinder height and at least one target data corresponding to the sub-geographic area.

Wherein, the height of the unit column represents a data value of the target data represented by a height value; for example 1 cm represents 10 target events. The preset cylinder height threshold value can be set according to an empirical value.

In specific implementation, the preset cylinder height threshold is 10 centimeters, the data values of the sub-geographic areas are 50, 35, 62, 78, 90 and 100 respectively, and then according to the target data 100 with the maximum data value in the at least one target data and the preset cylinder height threshold of 10 centimeters, the data value corresponding to 1 centimeter of the unit cylinder height is determined to be 10, and the cylinder heights of the target data corresponding to the sub-geographic areas are 5 centimeters, 3.5 centimeters, 6.2 centimeters, 7.8 centimeters, 9 centimeters and 10 centimeters respectively.

In a possible implementation manner, in this embodiment, the step of drawing a three-dimensional histogram corresponding to each target data based on the cylinder height of each target data corresponding to the sub-geographic area may be performed as shown in fig. 14:

in step 1401, a two-dimensional histogram corresponding to each target data is drawn based on the cylinder height of each target data corresponding to the sub-geographic area.

In step 1402, display information of the two-dimensional bar graph corresponding to each target data is determined; and according to the display information of the two-dimensional histogram corresponding to each target data, adjusting the display content of the two-dimensional histogram corresponding to each target data in the display interface respectively to generate the three-dimensional histogram corresponding to each target data.

In the embodiment of the present application, the display information of the two-dimensional histogram includes, but is not limited to, an offset value, an offset angle, a color value, and a shadow size.

In specific implementation, the geographic coordinate system of Echarts is used to locate the position information of each sub-geographic area on a map, each position information locates a histogram, and one histogram consists of three parts, namely a column bottom, a column body and a column top. The column bottom and the column top adopt color gradual change and shadow effect to form a three-dimensional effect, the column body adopts transverse gradual change, and the mode of adding transparency, curvature and straightness of trail lines and adding shadow forms the three-dimensional effect.

In a possible implementation manner, in order to generate a three-dimensional histogram corresponding to each target data in the sub-geographic area, it is further required to determine the position information of the three-dimensional stacked histogram in the sub-geographic area, so in this embodiment of the present application, the position information of the three-dimensional stacked histogram in the sub-geographic area may also be determined according to the steps shown in fig. 15:

in step 1501, area information of the sub-geographic area is acquired;

in step 1502, it is determined whether the area of the sub-geographic area is less than a predetermined area threshold;

if the area of the sub-geographic area is not smaller than the preset area threshold, in step 1503, using the center position of the sub-geographic area as the position information of the three-dimensional stacked histogram in the sub-geographic area;

if the area of the sub-geographic area is smaller than the preset area threshold, in step 1504, the center position of the sub-geographic area is adjusted based on the preset offset, and the adjusted position is used as the position information of the three-dimensional stacked histogram in the sub-geographic area.

In specific implementation, the area name and the coordinate data of the sub-geographic area are obtained, different sub-geographic areas are converted into coordinate data according to the GeoJson data, object data with corresponding relation among the area name, the area code and the area coordinate is set, no shielding is set and displayed for the corresponding three-dimensional stacked histogram of the sub-geographic area with the too small area, a preset offset is added to the coordinate data of the sub-geographic area, and the position information of the three-dimensional stacked histogram in the sub-geographic area is generated.

In a possible implementation manner, in the embodiment of the present application, a three-dimensional stacked histogram obtained by superimposing three-dimensional histograms corresponding to respective target data on a sub-geographic area in a three-dimensional map is displayed, and the steps may be performed as shown in fig. 16:

in step 1601, determining a starting height and an ending height of the three-dimensional histogram corresponding to each target data based on the cylinder height of each target data corresponding to the sub-geographic area;

in step 1602, based on the map data and the starting height and the ending height of the three-dimensional bar graph corresponding to each target data, performing superposition processing on the three-dimensional bar graph corresponding to each target data to obtain a three-dimensional stacked bar graph; and shown on a sub-geographic area in the three-dimensional map.

In specific implementation, according to the height of the cylinder of the target data of the previous category of the target event and the height of the cylinder of the target data of the next category, the starting height and the ending height of the cylinder of the target data of the next category are calculated, the three-dimensional map of the target geographic area is stacked according to the position information of the three-dimensional stacked histogram in the sub-geographic area, the abscissa value of each cylinder is the abscissa of the position information of the three-dimensional stacked histogram in the sub-geographic area, the coordinate data of the starting height and the ending height are changed according to the height of the cylinder, and finally the three-dimensional histograms of the target data are ensured to form a stacking effect in the same position information, as shown in fig. 17, the stacking effect is a display effect diagram of the final three-dimensional stacked histogram.

And displaying the numerical value information represented by the histogram above each histogram.

Thus, the user may manipulate the three-dimensional stacked histogram to reveal various sub-geographic regions in a step-by-step fashion.

In another possible implementation manner, the data presentation method provided in this embodiment of the present application may further be implemented as the steps shown in fig. 18:

in step 1801, in response to a data display operation triggered by a user, at least one piece of target data corresponding to each sub-geographic area in the target geographic area and map data of the target geographic area are obtained;

in step 1802, a three-dimensional map of the target geographic area and three-dimensional histograms corresponding to the sub geographic areas are generated based on at least one target data corresponding to each sub geographic area in the target geographic area and map data of the target geographic area, and three-dimensional stacked histograms obtained by superimposing the three-dimensional histograms corresponding to each target data are displayed on the sub geographic areas in the three-dimensional map.

Therefore, the three-dimensional stacked histogram of each sub-geographic area can be directly displayed only by clicking the data display application or the map application on the terminal after the information of the target geographic area and the target data of each sub-geographic area are stored in the background in advance without gradually displaying the three-dimensional stacked histogram on the three-dimensional map.
