Palette
Documentation
The PieChart, like other DevExtreme data visualization UI components, provides several built-in palettes. In this demo, you can use the drop-down menus under the UI component to choose a palette and change how it is extended when it has an insufficient number of colors.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
