RE: st: Change median plusmarkers in dotplot to median line

[Nick Cox <n.j.cox@durham.ac.uk>]

I flagged -stripplot- as SSC. What SSC means is explained in the Statalist FAQ. It means in your case that you must download -stripplot-, e.g. by using the -ssc- command.

Thanks Nick. I've tried the syntax you wrote but STATA does not recognize 'stripplot' command. i have Stata 11.1

unrecognized command:  stripplot
r(199);

This answer won't help. The median markers are marker symbols, so changing the symbol will not produce a straight line,

I don't think you can do this with -dotplot- short of cloning the program and changing the code.

-stripplot- (SSC) can get closer to what you want. You can look at its
-box- option.

This example shows other possibilities, but you would need to write some ad hoc extra code in the same style for your problem.

sysuse auto, clear

egen median = median(mpg) , by(foreign)

gen x1 = 0
gen x2 = 0.8
gen x3 = 1
gen x4 = 1.8

stripplot mpg, over(foreign) vertical stack /// addplot(rspike x1 x2 median if !foreign, horizontal || /// rspike x3 x4 median if foreign, horizontal)
