Re: st: line options for overlayed twoway kdensity plots

[Chris Hajzler <chajzler@gmail.com>]

Thanks, Austin.  I could not find this particular help file, but I
have located the proper commands for line options in the description
for scatter. The prefix I needed to use for my older version of Stata
was "cl" and not "l".

Cheers,
Chris
