Hello all, 

I did a search on google and I have also done a search from within the forum list and couldn't find an answer to my question; nonetheless, please forgive me if this is posted elsewhere. 

I am looking for a way to overlay the histograms of two variables in order to provide a visual comparison in a paper I'm writing. 

I'm not aware of something that does exactly this; close substitutes might be the following:

- Use the built-in boxplots: there you can specify several variables and they are shown side by side. (Although, to be honest, the plot design does not look super hot.)

- Overlay the smoothed histogram a.k.a. the kernel density estimate. Example:

<hansl>

open mrw list L = gdpgrow popgrow matrix dens = kdensity(L) gnuplot 2 3 1 --matrix=dens --with-lines --fit=none --output=display

</hansl>

cheers
