| What is the problem with gnuplot's contour?
The problem I was thinking of when I wrote that comment was that
gnuplot implements contour plots as a special type of 3D plot instead
of a 2D plot. So even though the final graph has only two dimensions,
it has a much different appearance than other 2D plots produced by
gnuplot and it is somewhat harder to combine a contour plot with
general 2D data.
I think it would also be nice if it could embed the contour levels in
the plot lines (I recall that there were plotting packages from the
mid-eighties (or even before) that could do this). Maybe gnuplot has
this feature now? I haven't checked.
