1 Jul 20228 minutes to read

The appearance of the SfFunnelChart can be customized by using the predefined palettes, custom palettes, and gradient which allows enriching the application.

Predefined PaletteBrushes

Currently, the SfFunnelChart supports only one predefined PaletteBrushes and it is the default brushes for the SfFunnelChart. The following screenshot shows the default appearance of the funnel chart.

<chart:SfFunnelChart x:Name="chart" 
                ItemsSource="{Binding Data}" 
                XBindingPath="Category"
                YBindingPath="Value">

</chart:SfFunnelChart>
SfFunnelChart chart = new SfFunnelChart();
chart.SetBinding(SfFunnelChart.ItemsSourceProperty, new Binding() { Path = new PropertyPath("Data") });
chart.XBindingPath = "Category";
chart.YBindingPath = "Value";

Custom PaletteBrushes

The SfFunnelChart provides support to define own brushes for the chart with preferred order by using the PaletteBrushes property as shown in the following code example.

<Grid>
    <Grid.Resources>
        <BrushCollection x:Key="customBrushes">
            <SolidColorBrush Color="#4dd0e1"/>
            <SolidColorBrush Color="#26c6da"/>
            <SolidColorBrush Color="#00bcd4"/>
            <SolidColorBrush Color="#00acc1"/>
            <SolidColorBrush Color="#0097a7"/>
            <SolidColorBrush Color="#00838f"/>
        </BrushCollection>
    </Grid.Resources>

     <chart:SfFunnelChart x:Name="chart" 
                ItemsSource="{Binding Data}" 
                XBindingPath="Category"
                YBindingPath="Value"
                PaletteBrushes="{StaticResource customBrushes}">
     . . .
    </chart:SfFunnelChart>
</Grid>
SfFunnelChart chart = new SfFunnelChart();
...
List<Brush> CustomBrushes = new List<Brush>();
CustomBrushes.Add(new SolidColorBrush(Color.FromArgb(255, 77, 208, 225)));
CustomBrushes.Add(new SolidColorBrush(Color.FromArgb(255, 38, 198, 218)));
CustomBrushes.Add(new SolidColorBrush(Color.FromArgb(255, 0, 188, 212)));
CustomBrushes.Add(new SolidColorBrush(Color.FromArgb(255, 0, 172, 193)));
CustomBrushes.Add(new SolidColorBrush(Color.FromArgb(255, 0, 151, 167)));
CustomBrushes.Add(new SolidColorBrush(Color.FromArgb(255, 0, 131, 143)));

chart.SetBinding(SfFunnelChart.ItemsSourceProperty, new Binding() { Path = new PropertyPath("Data") });
chart.XBindingPath = "Category";
chart.YBindingPath = "Value";
chart.PaletteBrushes = CustomBrushes;

Applying Gradient

The gradient for the funnel chart can be set by using the PaletteBrushes property of the funnel chart with the help of the LinearGradientBrush or RadialGradientBrush.

<Grid>
    <Grid.Resources>
        <BrushCollection x:Key="customBrushes">
            <LinearGradientBrush>
                    <GradientStop Offset="1" Color="#FFE7C7" />
                    <GradientStop Offset="0" Color="#FCB69F" />
                </LinearGradientBrush>
                <LinearGradientBrush>
                    <GradientStop Offset="1" Color="#fadd7d" />
                    <GradientStop Offset="0" Color="#fccc2d" />
                </LinearGradientBrush>
                <LinearGradientBrush>
                    <GradientStop Offset="1" Color="#DCFA97" />
                    <GradientStop Offset="0" Color="#96E6A1" />
