5 Manipulating Graphs
5.7 Displaying plans of graphs Many graphs are too large to be able to display in their entirety on the screen. As with any other window, you can use the scroll bars to display hidden parts of the graph. However, you can also display a plan view of the entire graph.
To display the plan view of any graph, hold down the Control key and select the graph. The graph is replaced by its plan view, similar to the one shown in Figure 5.10.
Figure 5.10 Example plan view
Each node in the original graph is represented by a rectangle in the plan view. The currently selected node is shown as a filled rectangle, and all other nodes are clear. You can select nodes in the plan view, just as you can in the normal view.
A dotted grid is drawn over the plan view; you can use this grid to alter the section of the graph that is shown in the normal view. The size and position of the grid represents the portion of the graph that is currently displayed in the normal view.
To return to the normal view, hold down the Control key and select the graph again. The part of the graph indicated by the grid in the plan view is displayed.
- To move the grid, so that a different part of the graph is shown in the normal view, hold down the Shift key and select and drag the innermost rectangle of the grid. The entire grid moves with the mouse pointer.
- To resize the grid, so that a different proportion of the graph is shown, hold down the Shift key and select and drag the outermost rectangle of the grid. The entire grid will resize. You can select any part of the grid except the innermost rectangle to perform this action.
