By default, the ZoomHeightMode property is exDefaultSize. If the ZoomHeightMode property is exCustomSize the ZoomHeight property specifies how large the chart will appear on the vertical axis.  If the ZoomHeightMode property is exControlSize the control updates the ZoomHeight property such that the chart will fit the control's client are on vertical axis. Use the ZoomWidthMode property to specify whether the ZoomWidth property is updated when the control is resized.

The following VB sample fits the chart to the control's client area:

With ChartView1
        .BeginUpdate
            .ZoomWidthMode = exControlSize
            .ZoomHeightMode = exControlSize
        .EndUpdate
End With

The following C++ sample fits the chart to the control's client area:

m_chartview.BeginUpdate();
m_chartview.SetZoomWidthMode( 2 /*exControlSize*/ );
m_chartview.SetZoomHeightMode( 2 /*exControlSize*/ );
m_chartview.EndUpdate();

The following VB.NET sample fits the chart to the control's client area:

With AxChartView1
    .BeginUpdate()
    .ZoomWidthMode = EXORGCHARTLib.ZoomModeEnum.exControlSize
    .ZoomHeightMode = EXORGCHARTLib.ZoomModeEnum.exControlSize
    .EndUpdate()
End With

The following C# sample fits the chart to the control's client area:

axChartView1.BeginUpdate();
axChartView1.ZoomWidthMode = EXORGCHARTLib.ZoomModeEnum.exControlSize;
axChartView1.ZoomHeightMode = EXORGCHARTLib.ZoomModeEnum.exControlSize;
axChartView1.EndUpdate();

The following VFP sample fits the chart to the control's client area:

With thisform.ChartView1
	.BeginUpdate
	.ZoomWidthMode = 2 && exControlSize
	.ZoomHeightMode = 2 && exControlSize
	.EndUpdate
EndWith
