Palettes
Palettes are a quick and easy way to define a skin for your chart view. A palette is a collection of several palette entries and each palette entry defines up to four colors – two fills and two strokes. Currently, only the Fill and Stroke properties are in use, the AdditionalFill and AdditionalStroke are not taken into consideration when applying a palette.

To apply one of these predefined palettes all you have to do is execute the following line of code:
Apply a Palette
this.radChartView1.Area.View.Palette = KnownPalette.Metro;
Here is how two of the palettes look like in action:

Figure 3: Windows 8
The predefined palettes consist of 8 palette entries which are applied to the series in a cyclic order. The first series is drawn with the colors from the first palette entry the second series is drawn with the colors form the second palette entry… the ninth series is drawn with the colors form the first palette entry and so on. If you would like to apply a palette entry specifically to a series you can do so using either one of the following line of code:
Specific Palette Entry
lineSeria.Palette = KnownPalette.Flower.GlobalEntries[0];
lineSeria.Palette = new PaletteEntry(Color.Yellow, Color.Red);
Predefined palettes cannot be edited , however, you can define your own palettes by inheriting from ChartPalette and creating a collection of palette entries. Here is an example:
Create a Custom Palette
public class CustomPalette : ChartPalette
{
public CustomPalette()
{
this.GlobalEntries.Add(Color.Yellow, Color.Red);
this.GlobalEntries.Add(Color.Yellow, Color.Blue);
}
}
Apply a Custom Palette
this.radChartView1.Area.View.Palette = new CustomPalette();
