Thank you Nick. Actualy what I was trying to do is
very simple (I thought).
Useing the auto data. I collapse to get percentages
and totals by -rep78- using:
.collapse (mean) percent=foreign (count)
total=foreign,by(rep78)
This yields:
rep78 percent total
1. 1 0 2
2. 2 0 8
3. 3 .1 30
4. 4 .5 18
5. 5 .818182 11
6. . .2 5
Note that these are the six bars to be plotted.
(actualy only 5)
I can graph using:
. graph bar percent, over( rep78)
But I want the variable -total- on on top of each
graph.
