ZoomMode

Purpose

This property is usually used top learn whether the object is currently zooming. Zooming is the process of using alternate extents for the graphs grid. For the Graph object, this is a read-only setting.

For the Scientific Graph, the developer can set ZoomMode = True, however, this can only be done with simple scientific charts with just one left and right y axis. MultiAxesSubsets is not compatible with setting ZoomMode = True programmatically.

Comments

This property is used in conjunction with ZoomMaxY, ZoomMinY, ZoomMaxRY, ZoomMinRY, ZoomMaxX, ZoomMaxTX, ZoomMinTX, ZoomMinX, ZoomMinAxis, ZoomMaxAxis, and AllowZooming.

With the scientific graph, to manually zoom a graph, set ZoomMinX, ZoomMaxX, ZoomMinY, and ZoomMaxY to any extents desired. Set the ZoomMode property to TRUE and call PEresetimage. For more information, see Chapter 7, Question 29.
