The heat map displays an icon of the geographic area in the data set in a special highlight form. Through the color depth and brightness of the heat map, you can intuitively and clearly see the regional data distribution, density and change trend, and get the data focus without data analysis, which is clear at a glance. The map-heat map provides a better experience for users to observe the degree of geographic data concentration in the form of markers.
Nowadays, many companies use heatmaps to do data analysis and analyze a kind of display effect of the market. The display effect of heatmaps is intuitive and clear. It plays a vital role in the analysis of business effects of enterprises. However, there are many ways to make heatmaps. Enterprises are very distressed, what should a simple heat map do? The following is a very simple method for everyone.
Examples based on Smartbi visualization tools:

Implementation steps
Create a heat map based on coordinates
Creating a heat map based on coordinates is based on the location information (longitude coordinates, latitude coordinates) of the location area where the data set created by the user exists, and can be used to set the location of the marker point based on the coordinates of the own data set.
Smartbi online heat map production step one:
Create a data set (including longitude, latitude, sales)
Smartbi online heat map production step two:
Create a new spreadsheet based on the above query. For the method of creating a new spreadsheet, please refer to the relevant chapters of the spreadsheet list report
In the spreadsheet toolbar, click the graphics option, the following Echarts drawing interface will appear, select "Map" for the graphics type
Step three of making Smartbi online heat map:
Choose how to load the map
Select "specified map", select "China" map
Step 4 of making Smartbi online heat map:
Data settings
Select the coordinates for "Map and Data Association Type", check the "Longitude Coordinates" field as the longitude, check the "Latitude Coordinates" as the latitude, check the "Sales" as the indicator, and select the heat map for the submap type
After selecting the data to save, you can see the heat map effect
advanced settings
If you are not satisfied with the default map effect, you can achieve the desired effect through configuration items.
a. Set the indicator style directly, click the setting button, and then click the "settings" button of the "sales" sequence to enter the sequence setting interface.
The setting items can set the legend position, text style, color matching type, interval name and color matching scheme. The legend position is used to set the position of the legend, and the text style is used to set the text font, font size and color of the legend.
The color matching type is used to set whether the legend is displayed continuously or in segments, and the effect is shown in the following figure
When the interval is continuous, there will be an interval name setting item below, which is used to set the display name of the legend. The default is low to high. When you click interval enumeration, the lower interval name will be hidden, as shown in the figure below; the color scheme refers to You can customize the color of the interval in the setting bar below, or you can select the color by checking the color scheme in the drop-down box
Interval continuous setting
Interval enumeration settings
b. To modify the relevant information such as the color of the map area, the color of the border, and the prompt information of the marker point, you can operate through the following interface.
The final effect of online heat map production
After the above configuration, click OK to save, and the final result is as follows:
