Property Value

Type	Description
TdxChartMouseAction	Mouse action settings for zoom-out operations in an XY diagram in large decrements.

Remarks

Users can left-click the plot area of an XY diagram while holding down the Alt modifier key to zoom the diagram out in large decrements. This action produces the same effect as a ZoomOut procedure call for the target diagram. To adjust the zoom decrement for this mouse action, use the LargeStep property.

You can use the ZoomOutMouseAction.ModifierKeys property to change modifier keys required to zoom diagrams out. Refer to the TdxChartMouseAction class description for detailed information on all available options.

Action Availability

Users can left-click the plot area of an XY diagram while holding down one or more modifier keys to zoom the diagram out in large decrements only if the following conditions are met:

• The ZoomOutMouseAction.Enabled property is set to True.
• The diagram’s ZoomOptions.AxisXZoomingEnabled or ZoomOptions.AxisYZoomingEnabled property is set to True. If only one of these properties is set to True, the zoom-out mouse action zooms the diagram out only by the corresponding axis.
