Hi Christian,
I've read your message a couple of times to see if I understand what
you are asking for. By "line labels at the boundaries only", do you
mean you only want contour lines labeled if they are near the X/Y axes
boundaries of the plot?
Just as a side, there are some "cnXXXXDrawOrder" resources you can set
to control when line contours, color filled contours, and labels are
drawn with respect to each other. The three phases (in order of when
they are drawn) are "PreDraw", "Draw", and "PostDraw".
For example, if you wanted to make sure that the lines from one
contour plot were drawn after the filled contours of another plot
(this is assuming the plots will eventually be overlaid on each other,
which you have to do in order for these DrawOrder resources to work
together), then you would set the "cnLineDrawOrder" resource to
"PostDraw" for the line contour plot, and "cnFillDrawOrder" to
"PreDraw" for the filled contour plot. You can also control the label
draw order with "cnLabelDrawOrder".
If this doesn't answer your question (which I'm guessing it probably
won't since your request seemed a little more specific), then please
email me personally and we'll figure it out.
Cheers,
