Hi Maarten,
I went about the simple (and brute-force) way by creating a
new variable equal to my earlier variable but with
"clearer" name and just recreated my graph. So it worked
for the time being but the -twoway- wasn't working. It
must be some error on my part because I haven't used
-twoway- before.
Anyway, thanks a lot for your suggestions. At least it's
useful to know that -twoway- can work with these plots too.
