Hi Thierry,
Thanks for using Syncfusion products.
We can achieve your requirement by setting Custom Palette
as per the below code snippet.
Code Snippet[XAML]:
<chart:ColumnSeries Palette="Custom" ItemsSource="{Binding
CategoricalDatas}" XBindingPath="Category" YBindingPath="Value" Label="First" >
<chart:ColumnSeries.ColorModel>
<chart:ChartColorModel>
<chart:ChartColorModel.CustomBrushes>
<SolidColorBrush Color="White"/>
<SolidColorBrush Color="#FF3B5C"/>
<SolidColorBrush Color="#F06B3C"/>
<SolidColorBrush Color="#FFFB6C"/>
<SolidColorBrush Color="#F0FB8C"/>
</chart:ChartColorModel.CustomBrushes>
</chart:ChartColorModel>
</chart:ColumnSeries.ColorModel>
We have prepared a sample based on this and you can find
the sample under the following location:
