Actually trying it suggests that no recourse to the Graph Editor is needed. clear set obs 3 gen cat = _n label def cat 1 low 2 medium 3 high label val cat cat foreach v in A B a b { gen `v' = 42 - uniform() + 0.5 } graph bar A B a b, over(cat) gen dummy = 0 graph bar A B dummy a b, over(cat, gap(*4)) legend(order(1 2 4 5)) There are two easy bits here: 1. A bar representing a zero value is of zero length and thus invisible. Hence you see a gap. 2. The corresponding legend entry can just be omitted. The difficult bit is if you want a gap that isn't the size of a bar. As earlier said, recourse to -twoway bar- is one way of getting that. Nick n.j.cox@durham.ac.uk Sue Sorry but can you be a little more specific about step 3? How would I edit out traces of -dummy- and what does it do?
