Took me some time to find out, but the solution to the question I posted
last week is rather simple in the end:
I wanted to create a population-pyramid-like graph for sex-specific cancer
frequencies (sorted by sex-specific rank) with all-positive barlabels):
Men Women
Prostate ************26******** *********32************* Breast
Colon ********19****** ******24*********** Colon
Lung *******14***** ****13******** Lung
Stomach ***7** **6*** Ovaries
etc.
(In fact, it's the same double bars but otherwise doesn't have too much in
common with the pop-pyramid.)
This graph can be done by combining two hbar graphs:
The men's graph is "mirrored" with the "yreverse" option (so that bars go
from right to left without having to use negative numbers).
The woman's graph has a "xalternative" option, so that category labels are
on the right.
For both sexes, each graph shows the n most frequent disease groups in
frequency order.
I do this by collapsing sex-specific cases by disease category and computing
a descending ranks var, by which the over-var is sorted in the graph
command.
