Changing the Node Layout

You can set default options to:

• Display the nodes vertically instead of using the horizontal default.

• Change the lines connecting the nodes to arrows to exemplify the directional flow from one node to another.

• Display function names in short or long form. The long form shows the function name and its argument-type signature. For example:

  Short form	handler_load_save
  Long form	handler_load_save(unsigned long, inputevent)

To change the layout of the nodes:

1. Choose Graph > Options.

2. Choose from among the following:

   Graph Layout	Select horizontal or vertical
   Use Arrowheads	Select yes or no
   Function Names	Select short or long (Call Grapher only)

3. Click OK.

To reset the layout, choose Graph > Reset Layout. All nodes return to their original positions in the graph. You can select nodes and drag them to other positions in the pane.

To select multiple nodes in the graph, hold down the Shift key and click each additional node.
