Yes, I tried that. Well, this may be a special case: I am trying to
plot contours of scattered (non-gridded) data. To see what is
happening, I try to overlay contours and the non-interpolated points.
Overlaying is the thing that does not work at all, here is what I
tried:
gplot({extracmds => 'plot \'table.dat\' with lines,', bottomcmds =>
'with points'}, $x, $y);
I guess there is a line feed at the end of extracmds that prevent this
working (of course it is needed in the intended use...).
Perhaps it is best to plot also the points from a file and in fact do
the whole thing outside PDL :-).
Why I always end up trying to do exactly the one thing that is not
possible with the tool I choose to use :-D....?
Thanks,
Kaj
