Re: st: hbar graph & colour

[Nick Cox <njcoxstata@gmail.com>]

Please think again. A fair fraction of the population is red-green
colour-blind.

I suggest looking at e.g http://colorbrewer2.org/ and selecting a
scheme that is more sensitive and is consistent with your other
desiderata. Otherwise how about

clear
input country   gdp   colour
1  100    1
2  110    2
3  240    3
4  50     1
5  10     1
end
graph hbar  gdp, asyvars over(colour) over(country, sort( gdp) descending) ///
bar(1, color(blue)) bar(2, color(orange)) bar(3, color(pink)) nofill

Even greater flexibility is given by recasting the problem as one for
-twoway bar-.
