RE: st: horizontal box plots and log scale |

Thanks Nick for your patience and assistance. I appreciate your advice. My main problem is simply that I cannot generate a horizontal box plot using the option ysc(log), and have not been able to since upgrading to Stata v11 (for Windows) onwards. If I include the option under -graph box- it works fine, but for -graph hbox- it gives a mess. Sadly, -stripplot- seemed to have a similar problem when I requested the log option. So I included code completely unrelated to my data so others could see if they had the same problem, or if this was something peculiar to my computer/s...

But if the values given are like your data, which are relative risks for various situations or studies, then I would not reach for a box plot at all. I would want to see all the values and so would use - graph dot- or -stripplot- (SSC) with an -over()- option. Such commands allow text labels for each value. When some values are very close together -devnplot- (SSC) can work better than -stripplot-. There is an example in my San Diego presentation, downloadable from the Stata website.
