The axes in Inspector contains the accumulated transform of the selected node path. You can find the equivalent transform by calling:
Code:
xform = node.getMatrix(viz.ABS_GLOBAL,node='name')
Where
name is the name of the selected node in Inspector for which you want to retrieve the axis transform from.
I just noticed that this command won't work if the name refers to a leaf (drawable) node. This will be fixed in the next release though.
