The Common Widget Settings
section in the dashboard property panel allows you to customize widget colors either based on unique data values or the index order of the data series, which can be configured using the Use Palette Color
option. By default, this option is disabled, rendering colors based on unique data values. When enabled, it applies colors based on the index order using the defined data color palette.
Note: For more details on theming and color palettes, please refer to the theming documentation.
