Dear Statalist users,
I am trying to plot the propensity score for treatment and
comparison group in one graph. So I use this command
twoway `vlist0' (rbar pscore1) (rbar pscore2) `vlist1' , yline(0,
lstyle(foreground) extend) ylabel() xtitle("Propensity Score")
ytitle("Density") legend(`l1' `l2' `l3' `l4') `options'
It turns out that half of the y axis labelings are negative. My
question is: how to get rid of the negative signs?
Please see the attached graph for an example.
Thanks a lot
Albert
