I have a Silverlight RadChart with one series and grouped by a field. I get different colors for each group but then the colors repeat for every 10 groups. How do I control the colors for each group my self or how do I increase the color range so that it repeats after 15 or more groups.

Hi Suresh,

We have introduced 10 default colors per theme. You can add more colors by using the available Palette Brushes functionality. Can you please let us know which theme you use and how many colors you need so we can suggest you more colors.

All the best,
Sia

I have got it working by using the below configuration. I would like to get suggestions from you on the colors though, I am using Vista theme. I would need at least 15 colors for my chart.

<telerikCharting:ChartDefaultView>
           
<telerikCharting:ChartDefaultView.ChartArea>
               
<telerikCharting:ChartArea PaletteBrushesRepeat="False">
                   
<telerikCharting:ChartArea.PaletteBrushes>
                       
<SolidColorBrush Color="Green" />
                       
<SolidColorBrush Color="Orange" />
                   
</telerikCharting:ChartArea.PaletteBrushes>
               
</telerikCharting:ChartArea>
           
</telerikCharting:ChartDefaultView.ChartArea>
       
</telerikCharting:ChartDefaultView>

Hi Sujana,



By default every theme that we ship supports up to 10 predefined colors. To extend them you are free to use Custom palette as described in this help topic. Below you may find the default colors for Windows8 theme:



<telerikCharting:ResourceDictionaryCollection x:Key="SeriesStyleResources" Repeat="True" >
        <ResourceDictionary>
            <SolidColorBrush x:Key="main" Color="#FF8EBC00" />
        </ResourceDictionary>
        <ResourceDictionary>
            <SolidColorBrush x:Key="main" Color="#FF25A0DA" />
        </ResourceDictionary>
        <ResourceDictionary>
            <SolidColorBrush x:Key="main" Color="#FFEB7A2A" />
        </ResourceDictionary>
        <ResourceDictionary>
            <SolidColorBrush x:Key="main" Color="#FFD8E404" />
        </ResourceDictionary>
        <ResourceDictionary>
            <SolidColorBrush x:Key="main" Color="#FF309B46" />
