Josip, here are a couple of hints. 1) a. Make sure your months are numerical and either interpreted or labeled as dates. See [U] chapter 27. b. This allows you to use -graph twoway bar- , which is for a numerical x, rather than -graph bar-, which is for a categorical x. c. Then you should be able to use the -xlabel(lowest(interval)highest)- option to determine which months to label. You may have to fiddle around with the starting value to get it right. See [G] graph twoway area for some hints. 2) When you are using -graph twoway-, you can overlay two plots, using the notation -graph twoway (bar olddeath month, plot_options) (bar newdeath month, plot_options), graph_options- (or the || notation). Make sure the olddeath data only go up to your chosen cutoff point and make a newdeath variable dealing with the tallest columns. Then fiddle around with appropriate ways of scaling the two y axes. Add some adornment to make the cutoff visible. See [G] graph twoway bar (p. 244) for some ideas to get you started. -- Håkon hakon.finneintef.no -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Dasovic, Josip Sent: 15. september 2004 08:30 To: statalist-digest@hsphsun2.harvard.edu Subject: st: Bar Graph Questions I have tried searching the appropriate places for help with bar graphs, but have come up empty-handed. I hope that list members may be able to help me with two questions regarding bar graphs. 1) I am creating a series of bar graphs of monthly numbers of deaths spanning almost ten years. I get exactly what I want, except for the labels on the x (i.e. categorical) axis. Stata, logically, keeps all the labels. I would like to keep a subset of the labels (e.g. Jan1991, August 1991, Jan1992, etc.) and haven't been able to find a way to do this. I have tried to remove the non-needed labels (i.e., Feb1991, March1991, etc.) from the variable itself and then create the graph, but to no avail. Any hints? 2) One of the columns is of a magnitude greater than the other columns. (While most columns values vary from 0 to 50, in one month the value is over 500). How do I fix the yscale so that it is appropriate (i.e., goes from 0 to 60, say, and place one of those fancy breaks in the one column that is much larger than the others?
