The following properties accept/return ChartHitTest values:
The ChartHitTest enumeration’s values are returned by the ChartHitInfo.HitTest property of a ChartHitInfo object. Note, that ChartHitInfo objects can be created by calling the chart’s ChartControl.CalcHitInfo method.
The following examples demonstrates how to handle the ChartControl.MouseMove event and calculate the hit information for the point which the mouse pointer is currently hovering over. Then, the name of the chart element located under the mouse pointer is shown within the form caption.
using System.Windows.Forms;
using DevExpress.XtraCharts;
// ...
private void chartControl1_MouseMove(object sender, MouseEventArgs e) {
ChartHitInfo hi = chartControl1.CalcHitInfo(new System.Drawing.Point(e.X, e.Y));
this.Text = hi.HitTest.ToString();
}
Imports System.Windows.Forms
Imports DevExpress.XtraCharts
' ...
Private Sub ChartControl1_MouseMove(ByVal sender As System.Object, ByVal e As MouseEventArgs) _
Handles ChartControl1.MouseMove
Dim hi As ChartHitInfo = ChartControl1.CalcHitInfo(New System.Drawing.Point(e.X, e.Y))
Me.Text = hi.HitTest.ToString()
End Sub
