SetCrosshairsPosition Method

Use this method to set the crosshairs to a specific x/y location on the chart.   This method is only available in the crosshairs mode (see SetCrosshairsMode).

[Visual Basic]
Sub SetCrosshairsPosition(XCrossCoordinate As Double, 
                          YCrossCoordinate As Double, 
                          XScaleIndex As Integer, 
                          YScaleIndex As Integer)
[C#]
void XYChartNETCtl.SetCrosshairsPosition(double XCrossCoordinate, 
                                         double YCrossCoordinate, 
                                         int XScaleIndex, 
                                         int YScaleIndex)
[C++]
void SetCrosshairsPosition(double, double, int, int)

Parameters

XCrossCoordinate

Indicates the plot's x-value to set the vertical crosshair at.

YCrossCoordinate

Indicates the plot's y-value to set the horizontal crosshair at.

XScaleIndex

Indicates which x-axis the XCrossCoordinate value pertains to.  Valid range: 0 to NumXScales - 1.

YScaleIndex

Indicates which y-axis the YCrossCoordinate value pertains to.  Valid range: 0 to NumYScales - 1.

Remarks

The crosshairs characteristics are determined by the Crosshairs property.

Example

XYChartNETCtl1 is the name of the XY Chart NET control instance placed on the form.

[Visual Basic]
Dim xCrossCoord As Double
Dim yCrossCoord As Double
Dim xScaleIdx As Integer
Dim yScaleIdx As Integer

xScaleIdx = 0      'X-axis scale index the crosshair's x-coord will be set against
yScaleIdx = 0      'Y-axis scale index the crosshair's y-coord will be set against
xCrossCoord = 24   'Vertical crosshair position
yCrossCoord = 500  'Horizontal crosshair position

'Position crosshairs; a Refresh call is not required 
XYChartNETCtl1.SetCrosshairsMode(True)
XYChartNETCtl1.SetCrosshairsPosition(xCrossCoord, yCrossCoord, xScaleIdx, yScaleIdx)
