Today, I will explain to you the use of map- multi-point flying line diagram in the data visualization software Diesel Smart Data visualization platform .
Data visualization , which can help you display data, statistical data, analyze data, and complete data interactive display through a visual interface and multiple statistical graphs in parallel .
First, we create a project and a page, operate on this page, select the component - map, and pull the multi-point flying line map. There are many other components in the map component that you can experience by yourself. For specific operations, you can search for technical articles related to Diesel Wisdom Numbers.
We see that the default arrows are flying to three places, namely Shanghai, Sichuan and Hunan. At the same time, the arrows flow in an orderly manner, which is very cool. What if you want to change different gathering places, or add more gathering places?
Select the flying line diagram component and click [Data] in the right navigation bar, as shown above.
Select the data source, focus the mouse on the data frame below, Ctrl+F full screen, and see the default data as follows:
Seeing the rules of these data, cooperate with the column prompt above, and the analysis is as follows:
The first column is the map code, usually 100000;
The second column is the classification, this classification is to increase the aggregation, and put the same classification data together;
The third and fourth columns are the longitude and latitude of the province. Usually, the middle position of the province is selected as the longitude and latitude (the specific longitude and latitude can be used in the Gaode map);
The fifth column is the region name, where the province name is displayed;
The sixth column is the data, here we take the size as an example.
If you want to add a gathering place, you need to add the corresponding data, the second column is mainly classified, such as ["10000", "Xinjiang Uygur Autonomous Region", 85.617733, 41.792818, "Xinjiang Uygur Autonomous Region", 100], this gathering place It is Xinjiang. If you need to flow like the arrows in the figure, you need to increase multiple pieces of data in this category, and the flow of these data arrows will be shown in the figure.
The above is a multi-point flying line diagram for static data display. Usually, we will use dynamic data as data display. Then we need to select the data source-selection, and use the database or API interface to obtain data. After obtaining the data, the data format may be different. It cannot be the same as the format of static data. At this time, we need to reassemble the data format into the data format of static data in the data processor below.
You can add, customize, modify, etc., custom handlers, or use the default handlers.
After configuring the data, you can click Properties to configure it. Under properties, you can modify the layer parameters, position, background, font and other effects to make the multi-point flying line diagram more beautiful.
The above are multi-point flying line diagrams, tutorials and demonstrations. The platform also provides more than 100 visual components . If you want to use more components, you can search online for "Disai Wisdom Numbers". More exciting things are waiting for you to discover!
