Nick-- Do the proposed solutions offer graphing bars +/- some number of standard deviations around the mean, rather than standard errors? I would think -vioplot- from SSC would be a better choice than either what the poster requests or a boxplot, but you could also adapt this approach for SDs: sysuse auto, clear levelsof rep78, loc(rs) miss loc g loc l foreach r of loc rs { qui su mpg if rep78==`r' if `r'>=. { loc l `l' `max' "`r'" loc r `max' loc max=`max'+1 } else { loc l `l' `r' "`r'" loc max=`r'+1 } loc g `g'||pci `=r(mean)-2*r(sd)' `r' loc g `g' `=r(mean)+2*r(sd)' `r' loc g `g'||scatteri `=r(mean)' `r', ms(o) msize(large) } tw `g' leg(off) xla(`l') On Mon, Nov 16, 2009 at 12:48 PM, Nick Cox <n.j.cox@durham.ac.uk> wrote: > But personally I'd prefer -stripplot- from SSC.
