Re: st: creating bar charts

[Scott Cunningham <scunning@gmail.com>]

Tacking this question onto my previous ones - in the help sections, I  
notice that what I'm attempting to do is done because the variables  
to be mapped onto the graph are actually different values.  For  
instance, in this code:

. graph bar (mean) tempjuly tempjan, over(region)

This is from the help on -graph bar- from a datafile called - 
citytemp-.  This produces exactly what I'm trying to do, where  
"region" in my case is "age", and the two variables side by side for  
each period are the white and black sex ratio.  But, my data usually  
is coded 1 or 2 for race, and not actually separate variables  
altogether for race.  In other words, if I had a variable called  
"bsr" for black sex ratio and "wsr" for white, then it'd be  
straightforward to reproduce the above as:

. graph bar (asis) wsr bsr, over(age)

But how do I accomplish the above if I use one variable (called  
"sexratio") which takes on two values (1 or 2 for white or black),  
and I wish to graph the white and black sex ratios side by side.   
When I do this:

. graph bar (asis) SexRatio if race==1 SexRatio if race==2, over(age)

I get an error that says, "invalid 'SexRatio' "
