My data is ~350 geographic units observed on 9 occasions. I want to be able to compare trajectories between geographic units. I've used xtline to eyeball this, but I'd like to have the equation of the lines to do it more systematically.

I've tried aaplot as follows:

Code:
foreach x of numlist 1(1)350 {
aaplot bandb wave if id==`x', both 
}
but this brings each plot up for a split second before moving on to the next one.

Is there a way to have the plots side by side as for xtline? And possibly to store the equations as a variable?
