I've tried a couple of times to overlay different types of graph, and not come up with a satisfactory solution. The low level commands of Stata 7 could be programmed to do this, but "graph combine" allows only for graphs to butt against each other. One example would be to place pies or barcharts at X-Y positions to make a simple map.
a) Is there an obvious solution I've overlooked?
b) Do other users see a general need?
c) Could it be implemented as an option to combine? Maybe: at(graphno r c xscale yscale) where r and c refer to absolute position in the plotting area (see help gph). Eg
graph combine gr1 gr2 gr3, at(1 23063 0 .5 1) at(2 23063 16001 .5 1) at(3 11531 20001 .1 .1)
