contour labels question

[Paul van Delst <paul.vandelst(at)noaa.gov>]

Hey there,

IDL> print, !version

The docs for the C_LABELS keyword for CONTOUR tell me:

"C_LABELS
 Specifies which contour levels should be labeled. By default, every other contour level
is labeled."

I don't get *any* labeling by default. Is there something other that needs to be done?
Specifying the number of levels? I'm surprised doing a simple

contour, z, x, y

doesn't give me labels every other contour.
