Rayko asked on 19 May 2010, 03:13 PM

Hello,
I'm trying to use a custom palette for the series in my bar chart because the Telerik-skin seems to contain only 6 default colors.
But when I create a custom palette the way shown below, the first 7 bar series are getting the default colors. Only series 8 and 9 are in the colors I created.
With a pie chart (1 series with 9 items) everything works fine.
Does anybody know this problem?

Best regards
Rayko

Hi Rayko,

Please, use this code:

ColorBlend[] seriesColors = new ColorBlend[] {

new ColorBlend(new Color[] { Color.Red, Color.Red}),

new ColorBlend(new Color[] { Color.Yellow, Color.Yellow}),

new ColorBlend(new Color[] { Color.Black, Color.Black}),

new ColorBlend(new Color[] { Color.Blue, Color.Blue}),

new ColorBlend(new Color[] { Color.White, Color.White}),

new ColorBlend(new Color[] { Color.Green, Color.Green}),

new ColorBlend(new Color[] { Color.MediumPurple, Color.MediumPurple}),

new ColorBlend(new Color[] { Color.Brown, Color.Brown}),

new ColorBlend(new Color[] { Color.Orange, Color.Orange}),

new ColorBlend(new Color[] { Color.Gray, Color.Gray})
