Dear gretl community, I was just wondering: is it somehow possible to create a scatter plot where markers depend on a categorical (but not dummy, i.e. not binary) variable? View / Graph specified vars / X-Y with factor separation looked promising, but it only allows dummy variables as separating factors, so the points can only be partitioned into two sets. Is it somehow possible to extend this to more than two...? (I thought the answer is surely positive as this is a very-very logical and obvious feature, but I couldn't figure out how to do this in gretl...) Thank you in advance, Tamas
