ZoomMode

Purpose

This property can be used to learn whether the object is currently zooming. Zooming is the process of using alternate extents for the graphs grid. For the Graph object / Pego this is a read-only setting.

For the Scientific Graph / Pesgo, the developer can set ZoomMode = True and related zoom extent settings ZoomMinX, ZoomMaxX. However, MultiAxesSubsets is only compatible setting ZoomMode with MultiAxesSubsets if AllowZooming is restricted to Horizontal. The incompatibility is specifically with Y-axis zoom extents (ZoomMinY/ZoomMaxY) which can't address multiple independent Y scales. 

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 considering MultiAxesSubsets use and or AllowZooming = Horizontal. Set the ZoomMode property to TRUE and call PEresetimage. For more information, see Chapter 7, Question 29.
