st: Specifying barlook_option on sorted bar graph

[Mathew Kiang <mathew.kiang@gmail.com>]

It seems like it should be a simple command, but I've given up in 
frustration and turn here for help.

I'd like to make a series simple bar graphs (let's say two graphs), one 
variable at a time (let's say mpg then cost) over a categorical variable 
(e.g., carmodel), sorted in descending order for each; however, the 
catch is I want a specific car model differentiated in both graphs (via 
one of the barlook_options).

graph bar mpg, over(carmodel, sort(1) descending)
graph bar cost, over(carmodel, sort(1) descending)

As far as I can tell, when I use a barlook_option like bar(#, color()), 
I have to specify the #th bar, which may not be the same across both 
graphs. I could go back and manually change each, but this quickly gets 
tedious with many different models or many different graphs.

Any help would be greatly appreciated!

Thanks,
Matt
