st: bar colours in -graph hbar, over()-

["Stephen P. Jenkins" <stephenj@essex.ac.uk>]

I am using the command

	graph hbar (asis) poverty , over(period) over(htype)

where period has 2 categories, and htype has 10 categories. The
command produces a graph exactly in the format I require, except that
I would like the bars for the first period category to be blue, and
the bars for the second period category to be red. How can I do this?

Search of on-line help, [G] manual, and Michael Mitchell's /A visual
guide to Stata Graphics/, has not yielded a solution, but I may have
missed something. Perhaps some -reshape- trick?

FYI the data are as follows

. clist htype period poverty, nolabel
