Thanks so much Nick for your very prompt reply. I had seen the FAQ... My sole reason for the transformation is to obtain equally spaced ticks for the values 0.4, 0.5, 0.66, 0.8, 1.0, 1.25, 1.5, 2.0, 2.5 (as it's using relative risk) so I didn't think it was necessary/desirable to transform the data. (Incidentally, I also tried -stripplot-, but had the same problem). However, if that is the only option, then obviously that will have to do.

Cox 9/05 How can I best get box plots on logarithmic scales? http://www.stata.com/support/faqs/graphics/boxandlog.html The essence of the problem is that -xsc(log)- just takes the graph you would have otherwise and transforms it logarithmically. You must transform the data first, draw the box plot, and then fix the axis labels. -mylabels- (SSC) may help with the last. I think you are wrong about Stata version here: this is in principle a problem with any version of Stata and a wired in boxplot command.
