How to customize a dashboard color scheme

The following example demonstrates how to customize a dashboard color scheme to color specified dimension values using predefined colors.

In this example, the dashboard contains a Pie dashboard item, whose dimension values and measures are colored by hue. The dashboard also contains a Chart dashboard item, whose dimension values are colored by hue. Dimension values, measures and corresponding colors are stored in a data table. 

To add custom colors to the dashboard color scheme (the Dashboard.ColorScheme property), ColorSchemeEntry objects are created. The ColorSchemeEntry class allows you to specify the following properties:
- The ColorSchemeEntry.DataSource property specifies a data source containing dimension values to be colored.
- The ColorSchemeEntry.DimensionKeys property allows you to specify required dimension values.
- The ColorSchemeEntry.MeasureKey property allows you to specify a measure key used to specify measures to be colored.
- The ColorSchemeEntry.ColorDefinition property sets a color used to color specified dimension values.
