The graphomate trees Extension supports some functions that can be used interactively at runtime. Many (but not all) of these functions are configurable on the Additional Properties Sheet.
Expand and collapse nodes
It is possible to expand and collapse nodes at runtime, to show or hide the child nodes of a node. You can adjust which nodes are shown at startup by changing the value of the properties Limit Depth and Level.
If a user hovers the mouse over a node, a tooltip is shown. The tooltip contains the nodes name as a well its value (from the Area Series).
