-graph bar- does not permit overlay. That is a -twoway- concept. That
you know.
If you attempted to translate -graph bar- into an equivalent -twoway-
statement, you would need to do more work. For example, stacking bars
calls for -twoway rbar- rather than -twoway bar- and you still need to
do more work to specify the cumulated coordinates. And -twoway bar- does
not permit -over()-, as indicated.
I'd imagine you're better off staying with -graph bar-. But if I
understand you correctly you'd need to -reshape- or -stack- your data so
that you could then call -graph bar- with two separate -over()- options.

Is there a way to "overlay" stacked bar charts? That is, using the
citytemp data I can go
webuse citytemp
graph bar tempjan tempjuly, over(region) stack
graph bar heatdd cooldd, over(region) stack
and get two separate graphs each over region. What I would like is one
graph, with the temp bar for each region paired with the corresponding
degree-day bar. I guessed the code would be something like the
following pseudo-code, which results in an error:
twoway (bar tempjan tempjuly ) (bar heatdd cooldd ), over(region) stack
option over() not allowed
r(198);
I've checked Mitchell's "Visual Guide to Stata Graphics", as well as the
web and the Statalist, and found no clues.
