Example

This example shows how to add a legend to a pie chart and adjust the legend settings.

1. To add a legend to the chart, assign a Legend object to the PieChartView.Legend property and use the following properties of this object to specify the legend orientation and position:

   • Orientation - display legend items in a row, from left to right.
   • VerticalPosition - place the legend above the chart diagram.
   • HorizontalPosition - align the legend horizontally to the center.

2. Set the Legend.Style property to a LegendStyle object and specify the following properties of this object to configure the legend appearance:

   • BorderColor and BorderThickness - configure the legend border.
   • BackgroundColor - specify the background color.
   • MarkerSize and TextIndent - change the size of markers, and set the distance between an item text and marker.
   • ItemsHorizontalIndent - specify the distance between legend items.
   • Padding - specify the distance between legend edges and content.
   • TextStyle - change the item text color and size.

3. To exclude points of the chart’s first series from the legend, set the VisibleInLegend property of this series to false.
