I don't know about PV-WAVE, but I learned not too long ago on
this newsgroup (much to my chagrin, after advising that it
*couldn't* be done) that you can do this in IDL with the
[XY]TickV and [XY]Ticks keywords. Here is a simple contouring
example:
x = [0.0, 0.8, 1.5, 2.0, 3.5, 3.7, 5.8, 6.5, 7.2, 8.8, 10.0]
y = Findgen(11)
data = Dist(11)
Contour, data, x, y, XTickV=x, XTicks=10
Cheers,
David
