From the sample I noticed that the colors come from separate sample dll. Any documentation for this?
 
Thank you,
Godwin

Please can anyone help? I tried to add CustomPalette to the ChartSeries:

<syncfusion:ChartSeries DataSource="{Binding ProductModel}"ColorEach="True" Palette="Custom" BindingPathX="Months" BindingPathsY="Sales">

<syncfusion:ChartStyleModel.CustomPalette>

<x:Array Type='Brush'>

<SolidColorBrush Color='Violet"></SolidColorBrush>

<SolidColorBrush Color='Indigo'></SolidColorBrush>

<SolidColorBrush Color='Blue'></SolidColorBrush>

<SolidColorBrush Color='Green'></SolidColorBrush>

<SolidColorBrush Color='Yellow'></SolidColorBrush>

<SolidColorBrush Color='Orange'></SolidColorBrush>

<SolidColorBrush Color='Red'></SolidColorBrush>

</x:Array>

</syncfusion:ChartStyleModel.CustomPalette>

</syncfusion:ChartSeries>

 

But it says:

Error 1 The attached property 'ChartStyleModel.CustomPalette' is not defined on 'ChartSeries' or one of its base classes. It's already been 3 days an I need some help.

 
Thank you

Hi Godwin,

 

Thanks for using Syncfusion products.

 

We have to set the CustomPalette property for the ChartSeries as like in the below codesnippet.

Code Snippet [XAML]:

                  <syncfusion:ChartSeries DataSource="{Binding ProductModel}" ColorEach="True" Palette="Custom" BindingPathX="Months" BindingPathsY="Sales">

                    <syncfusion:ChartSeries.CustomPalette>

                        <x:Array Type='Brush'>

                            <SolidColorBrush Color="Violet"></SolidColorBrush>

                            <SolidColorBrush Color="Indigo"></SolidColorBrush>

                            <SolidColorBrush Color="Blue"></SolidColorBrush>

                            <SolidColorBrush Color="Green"></SolidColorBrush>

                            <SolidColorBrush Color="Yellow"></SolidColorBrush>

                            <SolidColorBrush Color="Orange"></SolidColorBrush>

                            <SolidColorBrush Color="Red"></SolidColorBrush>

                            </x:Array>

                </syncfusion:ChartSeries.CustomPalette>

               </syncfusion:ChartSeries>

 

 Note: We will update the documentation in our next release volume 3 2013.

 

Please let us know if you have any queries.

 

Regards,

Vinoth Kumar J

Hi Vinoth Kumar,
 
Thank you, I am not able to resolve Syncfusion.Windows.Chart.ChartSeries.CustomPalette.
I'm using version 9.403.0.62. Is CustomPalette only available in some newer version?
 
Thank you.

Hi GodWin,

Thanks for your update.

We can achieve your requirement (CustomPalette) in  9.403.0.62 version using ColorModel property of ChartArea as in below code snippet.

Code snippet [XAML]: 

 <syncfusion:ChartArea.ColorModel>

 <syncfusion:ChartStyleModel x:Name="AreaColorModel" Palette="Custom">

 <syncfusion:ChartStyleModel.CustomPalette>

 <x:Array Type='Brush'>

 <SolidColorBrush Color="Violet"></SolidColorBrush>

 <SolidColorBrush Color="Indigo"></SolidColorBrush>

 <SolidColorBrush Color="Blue"></SolidColorBrush>

 <SolidColorBrush Color="Green"></SolidColorBrush>

 <SolidColorBrush Color="Yellow"></SolidColorBrush>

 <SolidColorBrush Color="Orange"></SolidColorBrush>

 <SolidColorBrush Color="Red"></SolidColorBrush>

 </x:Array>

 </syncfusion:ChartStyleModel.CustomPalette>

 </syncfusion:ChartStyleModel>

</syncfusion:ChartArea.ColorModel>

 

We have prepared a sample based on this and you can find the sample under the following location:

Please let us know if you have any queries.

Hi Muneesh, thank you, that worked, however, I did not need to add the array element in there.
 
The next question is, is there a way to bind a specific color to a datasource row with a specific property value?
 
Thank you,
Godwin
