Dear Stata forum,

I have a question about the graph bar command. So far, I have been using the following command which gives me satisfactory results.

Code:
graph bar (mean) edu1 edu2 edu3 edu4 edu5 edu6 edu7, by(native)
Note that edu1 are education binary variables for edu1 ==1 having postgraduate degree and zero otherwise, edu2==1 having bachelor qualification and zero otherwise and so forth.
Native takes on seven discrete values from 0-6 with zero being natives, one being Indians and so forth.

Here is my problem: I would like to add another variable, average real hourly wage, for every of the seven groups (natives plus six immigrant groups). This does not appear to be a straightforward task because I need to inlude a second Y axis with a different scale for wages on the right hand side (assuming that on the left hand side I have the proportions of people with various educational qualifications).

Nick, I am sure you might have an idea, although I do know that you are not very happy that I have not included a data example. I hope Nick or anyone else can give me a hint on this.

Best wishes.

Nico
