9                   Graph Layout

Using this dialog, you can ?gbeautify?h the graph layout of the model in the active canvas.

To change the layout of a model you need to take the following steps:

-         Open the Graph Layout dialog

-         Import the model into the Graph Layout dialog box

-         Run one of the available layout algorithms

-         Export the new layout.

 

The buttons at the bottom of the dialog are used to perform the following commands:

-         Import – imports the whole model from the active canvas to the Graph Layout dialog box.

-         Export – exports the graph from the Graph Layout dialog box to the canvas. This operation updates the positions of the elements in the canvas to the positions that have been set in the Graph layout dialog box.

-         Each of the buttons Sugiyama, CCL Sugiyama, Circle, Moen, Tree, Radial Tree executes the layout algorithm for the graph that is displayed in the Graph Layout dialog. Depending on the selected radio button, the layout algorithm can ?goptimize?h the positions of all nodes, the selected nodes only or the others, i.e., unselected nodes. The node selection should be executed inside the small canvas with standard mouse operation.
