I've been playing with
set contour surface
and seen some nice results. However one issue I'm having is that I can
select the contour values explicitly, as I'd like:
set cntrparam levels discrete 60, 300, 600, 1800
but then they appear in my legend as "60", "300", etc. In my current
case, those happen to represent seconds, so I'd like the labels to say
"A minute", "5 minutes", etc. I have not yet found a way to do this.
It would be really great if the discrete list could accept the same
syntax as the "set ?tics" commands, e.g.:
set cntrparam levels discrete ("A minute" 60, "5 minutes" 300, \
"10 minutes" 600, "Half hour" 1800)
Perhaps there's another way to achieve what I'm looking for, though?
Currently using 4.2, which is most convenient, but I've got 4.4 at home
and could upgrade here if I really needed to.
Thanks,
