The legend is an indicator of the data points displayed on the map. The legend area lists the values or range of values for each location and their corresponding colors on the visualization area. Using the legend effectively can help your users better identify the data points.
To configure the legend, first, go to the user interface designer and click on the map. Then press the blue Edit Legend button on the bottom of the settings menu.
Here, you can choose to display or hide the legend from the Enabled option. The font properties of the legend text can be customized from the Font Color, Font Family, Font Size, and Font Style options.
You can change the placement of the Legend from the Position property. Map colors can be configured from the Min Color and Max Color fields. The legend options will scale between the two colors and paint locations based on the Value Field or frequency of the data points.
The Number Format property can be edited to customize the formatting of the values shown on the legend.
