You can display the X and Y values while doing any Mouse Events like MouseUp, MouseDown, MouseHover, MouseLeave on the chart by using the methods GetValueByPoint which returns the X and Y values of the ChartSeries calculated from the mousepoint and GetPointByValue which returns the X and Y values of the mousepoint calculated from the ChartPoint. Using tooltip we can display the above data. The following code snippet must be given under the Mouse Event handler C#private void chartControl1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e) { //This gives the corresponding X and Y coordinates of the mouse point. Point mousePoint = new Point( e.X, e.Y ); //The GetValueByPoint method returns the X and Y values of the ChartSeries calculated from the mousepoint. ChartPoint chpt = chartControl1.ChartArea.GetValueByPoint( new Point( e.X, e.Y ) ); //The GetPointByValue method returns the X and Y values of the mousepoint calculated from the ChartPoint. Point pt = chartControl1.ChartArea.GetPointByValue( chpt ); string text = "Mouse point: " + mousePoint.ToString() + "\nResult of method GetValueByPoint: {" + chpt.X .ToString() + "," + chpt.YValues[0].ToString() + "}" + "\nResult of method GetPointByValue: " + pt.ToString(); //As mouse moves over the chartcontrol this displays the values as ToolTip. toolTip1.SetToolTip(this.chartControl1,text); }
VBPrivate Sub chartControl_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ChartControl1.MouseMove 'This gives the corresponding X and Y coordinates of the mouse point. Dim mousePoint As Point = New Point(e.X, e.Y) 'The GetValueByPoint method returns the X and Y values of the ChartSeries calculated from the mousepoint. Dim chpt As ChartPoint = ChartControl1.ChartArea.GetValueByPoint(New Point(e.X, e.Y)) 'The GetPointByValue method returns the X and Y values of the mousepoint calculated from the ChartPoint. Dim pt As Point = ChartControl1.ChartArea.GetPointByValue(chpt) Dim [text] As String = "Mouse point: " + mousePoint.ToString() + vbLf + "Result of method GetValueByPoint: {" + chpt.X.ToString() + "," + chpt.YValues(0).ToString() + "}" + vbLf + "Result of method GetPointByValue: " + pt.ToString() 'As mouse moves over the chartcontrol this displays the values as ToolTip. ToolTip1.SetToolTip(Me.ChartControl1, text) End Sub |
