Hello,

I've followed this article (which is great) : A WPF Pie Chart with Data Binding Support[^]

But I'd like to change the colors of the pie chart which are actually defined like this :

<Window.Resources>
        <x:ArrayExtension Type="{x:Type Brush}" x:Key="brushes">
            <SolidColorBrush Color="#FF8E01"/>
            <SolidColorBrush Color="#339933"/>
            <SolidColorBrush Color="#00AAFF"/>
            <SolidColorBrush Color="#818183"/>
            <SolidColorBrush Color="#000033"/>
        </x:ArrayExtension>
    </Window.Resources>
    <Grid>
        <StackPanel Orientation="Vertical">
            <c:PieChartLayout HorizontalAlignment="Center" Grid.Row="0" Grid.Column="0"
                              x:Name="piePlotter" PlottedProperty="" Margin="10">
                <c:PieChartLayout.ColorSelector>
                    <c:IndexedColourSelector Brushes="{StaticResource brushes}"/>
                </c:PieChartLayout.ColorSelector>
            </c:PieChartLayout>
        </StackPanel>
    </Grid>
</Window>

I'd like to use GradientColorBrush instead of SolidcolorBrush like this for example :

<RadialGradientBrush GradientOrigin="-0.1,-0.1" Center="0.075,0.015" RadiusX="1.05" RadiusY="0.9">
                <GradientStop Color="#FFB9D6F7"/>
                <GradientStop Color="#FF284B70" Offset="1"/>
            </RadialGradientBrush>

How can I do this ? I've tried multiple way without success...

Thank you,
