Appearance in WinUI Chart (SfCircularChart)

10 Jul 20266 minutes to read

The appearance of the SfCircularChart can be customized by using predefined palettes, custom palettes, and gradients, which allow enriching the application.

Predefined PaletteBrushes

Currently, the SfCircularChart supports only one predefined PaletteBrushes, and it is the default brushes for any circular series. The following screenshot shows the default appearance of the pie series.

XAML

<chart:PieSeries
    ItemsSource="{Binding Data}" 
    XBindingPath="Product" 
    YBindingPath="SalesRate">
</chart:PieSeries>

C#

PieSeries series = new PieSeries()
{
    ItemsSource = new ViewModel().Data,
    XBindingPath = "Product",
    YBindingPath = "SalesRate"
};

// Configure additional chart elements
chart.Series.Add(series);

Custom PaletteBrushes

The SfCircularChart provides support to define your own brushes for the series with a preferred order by using the PaletteBrushes property, as shown in the following code example.

XAML

<chart:SfCircularChart>

    <!-- Configure additional chart elements -->
    <chart:SfCircularChart.Resources>
        <BrushCollection x:Key="customBrushes">
            <SolidColorBrush Color="#4dd0e1"/>
            <SolidColorBrush Color="#26c6da"/>
            <SolidColorBrush Color="#00bcd4"/>
            <SolidColorBrush Color="#00acc1"/>
            <SolidColorBrush Color="#0097a7"/>
            <SolidColorBrush Color="#00838f"/>
        </BrushCollection>
    </chart:SfCircularChart.Resources>

    <chart:PieSeries 
        ItemsSource="{Binding Data}" 
        XBindingPath="Product" 
        YBindingPath="SalesRate"
        PaletteBrushes="{StaticResource customBrushes}"/>
</chart:SfCircularChart>

C#

SfCircularChart chart = new SfCircularChart();

// Configure additional chart elements
PieSeries series = new PieSeries();

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)));

series.PaletteBrushes = CustomBrushes;
chart.Series.Add(series);

Applying Gradient

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

XAML

<chart:SfCircularChart>

    <!-- Configure additional chart elements -->
    <chart:SfCircularChart.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"/>
            </LinearGradientBrush>
            <LinearGradientBrush>
                <GradientStop Offset="1" Color="#DDD6F3"/>
                <GradientStop Offset="0" Color="#FAACA8"/>
            </LinearGradientBrush>
            <LinearGradientBrush>
                <GradientStop Offset="1" Color="#A8EAEE"/>
                <GradientStop Offset="0" Color="#7BB0F9"/>
            </LinearGradientBrush>
        </BrushCollection>
    </chart:SfCircularChart.Resources>
    
    <chart:PieSeries
        ItemsSource="{Binding Data}" 
        XBindingPath="Product" 
        YBindingPath="SalesRate"
        PaletteBrushes="{StaticResource customBrushes}"/>
</chart:SfCircularChart>

C#

SfCircularChart chart = new SfCircularChart();

// Configure additional chart elements
PieSeries series = new PieSeries();

List<Brush> customBrushes = new List<Brush>();

LinearGradientBrush gradientColor1 = new LinearGradientBrush();

GradientStop stop1 = new GradientStop()
{
    Offset = 1,
    Color = Color.FromArgb(255, 255, 231, 199)
};

GradientStop stop2 = new GradientStop()
{
    Offset = 0,
    Color = Color.FromArgb(255, 252, 182, 159)
};

gradientColor1.GradientStops.Add(stop1);
gradientColor1.GradientStops.Add(stop2);

customBrushes.Add(gradientColor1);

series.PaletteBrushes = customBrushes;
 
chart.Series.Add(series);
