RE: st: RE: graph hbar - different colors for different groups defined by an external variables

Alice,

I think I finally found something that might work (albeit not very elegantly).  I got something similar to this to work with the auto data; some tweaking might be required to get it to work for your situation:

collapse (mean) g0, by(regione geo)
gsort -g0
gen g0sort=_n
separate g0, by(g0sort)
gen color="white" if geo=="Central"
replace color="gray" if geo=="South"
replace color="black" if geo="North"
forval j = 1/20 {         // Or however many regions there are
   local thislab=regione[`j']
   local lab `lab' `j' "`thislab'"
   local col=color[`j']
   local call `call' || bar g0`j' g0sort, horiz bcolor(`col') legend(off) ylabel(1(1)20, valuelabel angle(0))     // make 20=your number of regions
}

label define g0label `lab'
label value g0sort g0label

twoway `call'

Good luck!

Joe

Thank you Joe,

my command is

graph hbar (mean) g0, over(regione, sort(g0) descending label(labsize(vsmall)))

The graph that I would like to obtain have on the yaxis the name of the Italian regions, and the color of their bars should reflect their geographical position. For example, if the first region at the top of the y-axis  is Lombardy, and Sicily is the second one, I would like to color the first bar in black (color that corresponds to the North), and the second in gray (color of the South).

Thank you for your help

Alice

I want to plot them in a graph hbar, and I want to color the bars of the Northern regions in black, the bars of the Southern regions in gray, and the central regions in white. the external variable for the geographic ripartition of regions is called "geo".
