Setting the Plot background is an easy way to add some customization and contrast to your chart.

The following XAML markup allows you to set the background:

<c1:C1Chart.View>
    <c1:ChartView PlotBackground="#FF343434">
    </c1:ChartView>
</c1:C1Chart.View>

You can also set the PlotBackground property in code. Just specify your chart by name, and add the following code to the InitializeComponent() method:

chart.View.PlotBackground = Brushes.BlueViolet;
