Has anybody actually used plslabelfunc in a Fortran program? I've been
trying and it appears to be ignored. The demo program that follows (at
least for me) gives no indication that 'label_fmt' ever gets called. So I
thought I'd just check in case I'm doing something silly before I report a
bug.
I'm using plplot 5.9.9 on Manjaro Linux (Arch derivative) with gfortran
4.7.2.

==== DEMO PROGRAM =====
module fmtf
use plplot
implicit none
contains
subroutine label_fmt(axis, value, label, length)
integer :: axis, length
real(kind=plflt) :: value
character(len=length) :: label
print *, axis, length, value
if (axis == 1) then
write(label, "('x',f3.1,'x')") value
else
write(label, "('y',f5.3,'y')") value
end if
print *, label
end subroutine label_fmt
end module fmtf
program axis_fmt
use plplot
use fmtf
implicit none
call plparseopts(PL_PARSE_SKIP)
call plinit()
call plslabelfunc(label_fmt)
call plenv(0._plflt, 8._plflt, 0._plflt, 12._plflt, 0, 0)
call plend
end program axis_fmt
