Action Availability

The Marquee Zoom tool is available to users only if the following conditions are met:

• The MarqueeZoomMouseAction.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 Marquee Zoom tool can zoom the diagram in only by the corresponding axis.
