====== Graph ======

The 2d Graph panel (panels/2d/graph) is a powerful tool for understanding and navigating the graph structure in smaller GroIMP models.

The menu of this graph allows to change the ([[01_user_documentation:03_interacting_with_groimp:02_panels:03_2d:02_graph:02_layouts|layouts]] (Layout > Edit), to change between different [[01_user_documentation:03_interacting_with_groimp:02_panels:03_2d:02_graph:01_descriptors|Graph descriptors]] (Graph > Edit), to redraw the graph / reapply the layout (View > Redraw),  collapse and expand all node (View > Collapse all, View > Expand all) and to save the currently displayed picture (View > Snapshot)

Starting with GroIMP 2.2.2 it is possible to enable auto redrawing of the 2D Graph in the preferences. This will automatically redraw after every graph changing event.


===== Collapse / expand =====

By double clicking on a Node on the 2d graph the node can be collapsed, meaning all its children are hidden. A collapsed node can be identified on the round shape (see image above lower right corner). Double clicking on a collapsed node expanse it again. 

Node with more than 10 direct children will be automatically collapse when the 2D graph is opened.
