Hello David,
So it means that 'axis' becomes a 100% worthy plot command when you
use /Save (So /Save means "Yes, save the !y.crange")? And then use
yrange for the range. And it was the range that made me use another
'plot' command in my real implementation. Thanks, now I can tidy up my
code (if still possible).
Regards,
Joost

Well, when you don't particularly care if the axis auto-scales.
Most of the time when I use the axis command I am using it to
create a second axis, not one identical to the first. I may
have no reason to exactly scale the second axis.
I think your problems come about because you are doing
two PLOT commands. The normal procedure would be to do
one PLOT command, then set your second axis (using the SAVE
keyword), then OPLOT onto that second axis. See this article:

Cheers,
David
