Configure chart style

The following style settings are specific to the symbol map. For common chart style settings, see Configure Chart Style.

1. Geographic area

   Configure the following settings:

   • For Display Range, select Auto or Custom.

     Note

     • Auto adjusts the range based on the data. Custom lets you set the range manually. In interactive analysis scenarios, the range is always automatically adjusted based on the data.

     • Custom display ranges currently support only continents, countries, and regions, provinces, and cities in China.

     

     You can also enable Manual Adjustment. The current centroid and scaling values are automatically generated, and you can modify them.

     

   • In the Outline and Fill section, configure the background color of the area and the color of the outline.

     Note

     Outlines are not supported for some regions.

     

   • Select Enable Drag and Enable Zoom to allow users to drag and zoom the chart in the preview of the data visualization screen.

     

   • In the Outer Outline Streamer section, enable or disable the streamer effect. When enabled, you can configure the Streamer Color (Solid/Gradient), Thickness, Speed, and Length.

     

2. Base map

   In the Display Base Map section, you can select one of the Gaode Map styles to use as the base map.

3. Symbol

   Configure the Symbol Type, Symbol Size, and Symbol Opacity.

   • Symbol Type:

     • If you configured a field for Symbol Type/Dimension on the Fields tab, symbol styles are automatically generated based on the dimension values. You can modify the symbol styles in this section. In this example, Symbol Type is set to the Outlet Type field, with different symbols for directly-managed and franchised outlets across regions.

       

     • If you did not configure a field for Symbol Type/Dimension on the Fields tab, you can manually select an icon or upload an image link.

       

   • Symbol Size: Drag the slider to change the symbol size.

     

   • Symbol Opacity: Drag the slider to change the symbol opacity.

     

4. Data label

   Configure the following settings:

   • Show Data Label:

     If you create a map using the Area Name mode, you can display both the area name and the measure.

     If you create a map using the Latitude and Longitude mode, you can display the latitude and longitude and the measure. If you have configured a Location Label/Dimension, you can also display the location label.

     

   • Label Display Mode: Smart Display and Full Display are supported. Smart Display is suitable for maps with many place names.

     

   • Text Style: Set the text style for the Area Name, Latitude and Longitude, and Measure data labels.

     

5. Tooltip

   Configure the Background Color, Text, Enable Tooltip, and Carousel settings.

   

   Enable Tooltip is enabled by default. The tooltip appears when you hover over an area.
