With DXCharts, you can fully customize the appearance and behavior of chart titles. For example, this sample illustrates how to display a group of check boxes, which control series visibility, in a chart title’s area.

To accomplish this task, it is necessary to define a WrapPanel with a set of CheckBox elements, and bind their check state to a Series.Visible property of the corresponding series. Then this WrapPanel can be placed as a chart title into a ChartControlBase.Titles collection.

View Example

MainWindow.xaml.cs

using System.Windows;

namespace CustomChartTitles {
    public partial class MainWindow : Window {
        public MainWindow() {
            InitializeComponent();
        }
    }
}

MainWindow.xaml

<Window x:Class="CustomChartTitles.MainWindow"
