I've done this with R. I can't compare it with gnuplot, because I've had
the same problem getting gnuplot to do contours. I know I've seen it
suggested that gnuplot can, though.

I will not say that R is great for plots though. Extreme control over
axes and text labels is a real pain.

The attached plot was created with the following R command:

contour(c(2008:2060),breaks[2:19],d,col=terrain.colors(20),
zlim=c(0,40))

d is a sample of modeling results for Lake Powell elevation. :)

I would also say that the colors, etc. on this plot are not great, but
it is an example.
