Hi. I am currently evaluating Rapidminer and going through the tutorial, so, my apologies if I am missing something obvious.
I have trouble getting decision tree graphs displayed right: the tree is see in Rapidminer Studio "results" pane is quite different from the screenshots online. Where labels are supposed to be, i see only a very tall grey rectangle (see attached PNG picture).
Any suggestions to fix this?
