st: second y-axis in graph bar

[Harry Telser <telser@soi.unizh.ch>]

Dear Statlist users

I want to draw a bar chart with two y-variables relating to two 
different axes.

The graph should look something like that:

. sysuse auto
. graph bar weight length, over(rep78)

but with "length" relating to a second y-axis on the right side.

Is there any way to define a second y-axis in "graph bar" command? I 
know it can be done with "twoway bar" but I did not manage to get the 
look as in "graph bar".

Any help is appreciated.

Harry
