[Plplot-general] unable to open plots "plenv: Invalid xmin and xmax..."

[Michael D. <mj...@ph...>]

Dear colleagues,

We recently installed the plplot 5.1.0 on a Redhat Linux system. We then
found that c programs that worked last year can no longer open any plots:

#####################################
 ...
 <25> jpeg       JPEG File
 <26> pstex      Postscript/LaTeX device
 <27> null       Null device

Enter device number or keyword: 1

*** PLPLOT ERROR ***
plenv: Invalid xmin and xmax arguments, aborting operation
################################################

The c-code compiles fine and only has the following calls:
        plinit();
        plenv(xmin,xmax,ymin,ymax,just,axis);
        plend();
The only clue to the problem is that in some cases, it doesn't occur when
you log in to the host from another machine to run the same code so
perhaps it is an X-windows issue? Note that we get the same behaviour if a
postscript file output is chosen so it is not a simple X-display issue.

We would be very grateful for any suggestions.
Thanks for your time,
   Michael Drinkwater
