-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. Nick n.j.cox@durham.ac.uk Devra Golbe 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. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
