Scott,

I expected 50_59 to be above 50_50 because in a horizontal bar chart,
the categorical axis is called the x axis, even though it is vertical.

I have managed to produce a triangle while varying only one coordinate
in the auto.dta dataset:

sysuse auto,clear
graph hbar mpg, over(head) text( 20 25 "20_25"  20 15 "20_15" 20 10
"20_10") bar(1, fcolor(gs15))

Are you getting a triangle or a straight line when you run that code
(is it a problem with my version/install of stata?  I'm using 10.0...)

Thanks,
Dan
