Examples

This example demonstrates how to modify the Crosshair Cursor's appearance using the ChartControl.CustomDrawCrosshair event.

In this sample, crosshair content is displayed in a legend. For this, set the CrosshairOptions.ContentShowMode to the Legend value that the CrosshairContentShowMode enumeration contains. Note that you can specify the crosshair's content show mode for the specified series using the XYSeries2D.CrosshairContentShowMode property.

Use the CustomDrawCrosshairEventArgs.CrosshairLegendElements property to obtain the crosshair legend elements' collection.

To customize each crosshair legend element options, use the CrosshairLegendElement class properties.

using System.Windows;
using System.Windows.Media;
using DevExpress.Xpf.Charts;
namespace CustomDrawCrosshair {
    public partial class MainWindow : Window {
        const int ColorSelectorValue = 10;
        public MainWindow() {
            InitializeComponent();
        }
        private void OnCustomDrawCrosshair(object sender, CustomDrawCrosshairEventArgs e) {
            foreach(CrosshairLegendElement legendElement in e.CrosshairLegendElements) {
                legendElement.Foreground = (legendElement.SeriesPoint.Value > ColorSelectorValue) ? Brushes.Green : Brushes.Red;
                legendElement.LineElement.Brush = legendElement.Foreground;
                legendElement.AxisLabelElement.Background = legendElement.Foreground;
            }            
        }
    }
}
