Zoom trees

Is it possible to individually programmatically zoom in and out trees?
If you have more than one tree on the screen, I only want to zoom in one tree and not the other.


The Diagram.scale property, which is modified by the zoom commands, applies to everything that the user can see in the diagram.

But you could adjust the spacing between the nodes and/or change the scale of the nodes (the GraphObject.scale property).

Works thanks!
