SetZoomWindow Method

Use this method to perform a zoom to the specified min and max values. This method is only available in the zoom mode (see SetZoomMode).

Syntax

[Visual Basic]
Sub SetZoomWindow(newXMin As Double, newXMax As Double, XScaleIndex As Integer, newYMin As Double, newYMax As Double, YScaleIndex As Integer)

[C#]
void XYChartNETCtl.SetZoomWindow(double newXMin, double newXMax, int XScaleIndex, double newYMin, double newYMax, int YScaleIndex)

[C++]
void SetZoomWindow(double, double, int, double, double, int)

Parameters

newXMin: Indicates the plot's new minimum x-value for the passed in x-scale.
newXMax: Indicates the plot's new maximum x-value for the passed in x-scale.
XScaleIndex: Indicates which x-axis the new min and max values pertain to. For charts with multiple x-scales, all other scales are zoomed to its corresponding values. Valid range: 0 to NumXScales - 1.
newYMin: Indicates the plot's new minimum y-value for the passed in y-scale.
newYMax: Indicates the plot's new maximum y-value for the passed in y-scale.
YScaleIndex: Indicates which y-axis the new min and max values pertain to. For charts with multiple y-scales, all other scales are zoomed to its corresponding values. Valid range: 0 to NumYScales - 1.
