-meansdplot- is a program from Phil Ender from UCLA:
meansdplot from http://www.ats.ucla.edu/stat/stata/ado/analysis
meansdplot. Plot mean and stendard deviation for multiple groups. /

package / distribution-date: 20071117
Please remember that you are asked to explain _where_ user-written
programs you refer to come from.
You have, I think, found a bug in -meansdplot-. The program accepts an
-if- qualifier [not a statement] but it only affects part of the plot
and does not affect the main calculations.
One work-around for what you want while Phil fixes the code is
forval j = 1/3 {
preserve
keep if group == `j'
meansdplot var1 var2
restore
}
-sttripplot- (SSC) and -dotplot- are other commands with broadly
similar aims. It is also always possible to -collapse- a dataset
-by()- some group variable and plot summary statistics directly.
