st: hbar graph & colour

[María Edo <mariaedo@gmail.com>]

Hello,

I need to construct a horizontal bar graph using three colours: two
different colours to highlight two particular bars (say, red and
green) and one colour for the rest of the bars (say, blue).

So far, I have managed to get two colours in the graph by using the
-over- option:

input country   gdp   flag1 flag2
1  100    0       0
2  110    0       1
3  240    1       0
4  50     0       0
5  10     0       0
end
graph hbar  gdp, asyvars over(flag1) over(country, sort( gdp)
descending) bar(1, color(blue)) bar(2, color(red)) stack

To get the graph I need, country "2" should appear in green.

I am sure there is a trivial way of achieving this, but I haven't been
able to find it.
Many thanks,

Maria
