The class describes the common interface supported by the 2D or 3D GraphColumnView.
|
|
|
19 |
This Viewclasses provide a lot of functionality for showing and manipulating graphs
|
|
|
20 |
described through to a GraphColumn description. Each change in a graph description
|
|
|
21 |
immediately take affect in the garph view.
