I am having a problem with clipping. As I understand it, XYOUTS has
clipping turned off
by default, but setting NOCLIP=0 should turn clipping back on and
prevent text from
being written outside the plot axes. I've discovered that this works
fine as long as you
use Hershey fonts, but it does not work when you use hardware fonts.
Here is a
program illustrating the problem:
; sample code to demonstrate peculiar clipping behaviour.
; When hardware fonts are turned on, clipping is not handled properly.
!p.multi=[0,1,2]
!p.font=-1 ; turn off hardware font
plot,[0,1,2]
xyouts,.5,2.05,'this shows up' ; label off the top
xyouts,1.5,2.05,'this is clipped properly',NOCLIP=0 ; turn on clipping
!p.font=0 ; turn on hardware font
plot,[0,1,2]
xyouts,.5,2.05,'this shows up' ; label off the top
xyouts,1.5,2.05,'this should not show up',NOCLIP=0 ; turn on clipping
end
;******************************
I have not seen this documented as a 'feature' and it is causing lots of
problems with
my plots. I suspect that there is a workaround using the !p.clip array,
but I have not
tried to figure it out yet. Am I alone in having had this problem?

I tend not to use the hardware fonts on-screen because they cannot be
rotated - it makes Y-axis labels look pretty crude. Usually one of the
Hershey fonts suffices, and when I want to make hard copy, I use one of
the Postscript fonts.
I realize that's not much help: sorry.
Cheers,
Liam.
