[Gretl-users] Re: Histogram with two variables

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
sven
