This document describes how to select a palette for painting a chart’s series (or their individual points). The same steps will define an individual palette for painting a chart’s indicators.

You can choose a precomposed palette for painting a chart’s series or their points via the WebChartControl.PaletteName property.

To define a similar palette for all the chart’s indicators, use the WebChartControl.IndicatorsPaletteName property.

The following images demonstrate a chart with different palettes (using the Default appearance). For the complete list of precomposed palettes, see PaletteRepository.PaletteNames.

PaletteName = Concourse	PaletteName = Apex	PaletteName = Grayscale

Additionally, within the selected palette, you can specify the base color of this palette, to assign a spectrum based on this color. The base color is specified by an integer value of the WebChartControl.PaletteBaseColorNumber property. Its effect is demonstrated in the following image (with an example of the Concourse palette).

PaletteBaseColorNumber = 1	PaletteBaseColorNumber = 3

When the WebChartControl.PaletteBaseColorNumber property is set to 0 and the SeriesViewColorEachSupportBase.ColorEach property of a series is enabled, the palette is used to paint the individual points of that series.

When a palette base color number is not equal to 0, the SeriesViewColorEachSupportBase.ColorEach property paints series points based on a composition of the specified color.

ColorEach = true PaletteBaseColorNumber = 0	ColorEach = true PaletteBaseColorNumber = 1

When none of the demonstrated approaches provide the desired result, you have the option to create a custom palette.

In addition, you can enable your end-users to choose palettes and appearances for a chart themselves. The corresponding example is available in our Code Central database at How to provide end-users with the capability to change a chart’s appearance on the fly.
