Presenting a projection

 

You can show the descendants of a selected group of nodes (at a certain depth) by creating a projection. The descendants are presented in a projection window. To produce a projection:

1. Select one or more nodes to be the roots of the projection.
2. Choose Settings from the Options menu.

   A Settings dialog appears.

3. Adjust the Projection Depth slider to the depth you want.

   If the slider is -1, the projection depth is infinite and a projection would display the ``leaf'' nodes of the hierarchies rooted at the selected root nodes. If the slider is 0, a projection would display only the selected root nodes.

   Otherwise, a projection displays children nodes at the specified depth. Leaf nodes are included in the projection if the slider value is set too deep for certain branches of the hierarchy.

4. Choose Projection from the Navigate menu.

   A new Projection window appears, containing a union of all nodes that are exactly at the specified depth below the selected nodes. The names of the selected nodes that were projected appear on the title bar of the projection window.

   

Note: Projection window s do not support graph modifying operations.
