st: help with twoway bar chart using by option

[Miranda Kim <mk@mrc.soton.ac.uk>]

Hello,
I am a Stata v11 user, and would very much appreciate any suggestions on 
the following:

I would like to produce a twoway bar chart using the by option, for example:

For example:
sysuse auto, clear
collapse (mean) mean = mpg, by(foreign rep78)
twoway bar mean rep78, by(foreign)

I would then like to insert a different text box in each plot area.

So in the example above, how could I insert a text box in the “Domestic” 
plot area that says “hello” and a textbox in the foreign area that says 
“goodbye”?

At present, I only know how to insert a textbox that is replicated in 
both plot areas...

The graph I am producing has many more formatting specifications to make 
it look nice, but I have just used the above example to help illustrate 
the specific issue I cannot, at present, resolve.

Many thanks,
Miranda
