TreeViewer
is used to visualize hierarchical data. The chart builds a tree structure with up to three levels for a given dataset. The columns are selected based on a number of categories in them. To change the order of columns, add new levels to the initial hierarchy or remove the existing ones, edit the hierarchy
property.
The chart responds to data filters and rows selection. The only difference with the native viewers behavior is that the selection of rows in TreeViewer
has limited interaction. The selection works on clicks with applied modifier keys (Shift
adds to the selection, Ctrl
toggles the selected state, see more in the wiki); while a regular click on a node is reserved for expanding or collapsing branches of the tree.
In the viewer properties, you can adjust marker settings, change a tree layout, or toggle certain behaviors, such as animation, expanding or collapsing nodes, etc.
