Reference for -labmask- SJ-8-2 gr0034 . . . . . . . . . . Speaking Stata: Between tables and graphs (help labmask, seqvar if installed) . . . . . . . . . . . . N. J. Cox Q2/08 SJ 8(2):269--289 outlines techniques for producing table-like graphs Nick n.j.cox@durham.ac.uk Nick Cox This information to me supports my earlier suggestion. Given this kind of problem my focus would be entirely on creating a results set, alongside or independently of your dataset. If you create an axis variable running 1,2,3,... and associated text labels, then a helper program -labmask- was written up in the Stata Journal which maps values to value labels. A strategy would be * initialise variables gen axisorder = _n gen label = "" gen num1 = . gen num2 = . local obsno = 1 * loop over possibilities quietly foreach <loopinfo> { replace label = "<text for this situation>" in `obsno' replace num1 = <result for this situation> in `obsno' local ++obsno } labmask axisorder, val(label) graphics in terms of axisorder, num1, num2, etc. I don't see that you need StataCorp to fix the graphics. Conversely, a fix general enough to tackle what you want to do would probably result in a syntax very difficult to understand. A limitation of the graph you displayed is that very space is devoted to data and that the two sets are difficult to compare precisely. Overlaying the graphs seems indicated. Nick n.j.cox@durham.ac.uk Fred Wolfe I hope I can explain it it. First, let me say that I think I can figure out ways to do this by reorganizing the data. But the time involved in doing this is (at least for me) too long. Consider the example below: http://screencast.com/t/NjUwNmE3YTMt This is a special case of a general problem. Special because in this instance it is a results data set that was made by copying results from Stata to a new data set. In this instance, each named line represents a different variable. The code for one side of the graph is: use raoadotplotdata, clear graph dot (asis) age - all ,ascat ylab(.5 [.1] 1) exclude0 schem(bw) ytit(Concordance coefficient) xsize(4) ysize(5.3) by(type,note("")) Now, what I would really like to be able to do is to not use "by" and have both types of symbols (RA and OA) be displayed on each line. If I simply do over(), the groups are placed far apart. So, in general, I would like a simple way to manage multiple variables and to display the by group or over group results on the same line or immediately below the same line. I have looked at stripplot, the manual, and Michael's book to no avail. It is usually that when I come to conclusions like this there is a simple solution that I have overlooked. I hope it is the case now.
