Subject: st: Possible to have different colours for by() groups in
histogram?
Hello,
I would like to know if it is possible in Stata to have different colours
for plots in histograms created using the by() option. For instance, if I
would like to plot frequencies of a Likert scale about the ease of a process
(from 1 to 5) in two separate groups, I can generate a nice histogram using
the by() option, but both "sides" (or plots) of the graph are the same
colour.
For instance,
input group ease
1 1
1 2
1 3
1 3
1 3
1 3
1 4
1 5
1 5
2 2
2 2
2 2
2 3
2 3
2 4
2 4
2 5
2 5
end
graph twoway histogram ease, by(group) discrete frequency xtick(1(1)5)
xlabel(1(1)5) gap(5) color(red)
This gives me a histogram, but I would like a different colour for each plot
- say red for the plot on the left and blue for the one on the right.
I am sure there is a trivial way of achieving this, but I haven't been able
to find it. The barlook_options are not valid for histograms, and using the
graph editor to alter the colour also results in both plots becoming the
same colour.
Many thanks,
Phil
