Hi,
a colleague of mine found something which looks like a bug in
CONTOUR to me:
he plotted filled contours, specifying levels and color levels
and he got one color that was not filled but left blank. We tried to
shift the colors in the color table or specify different levels, but
nothing changed and the blank "stripe" remained at the same spot. Now
this morning, he told me that he had used the /OVERPLOT option, and when
he removed it, everything worked fine. But why should overplot have any
effect on the operation of contour itself ???? Note: this is *not* the
same problem discussed here previously, because it wasn't the lowest
level that did not get filled.
Regards,
Martin
PS1: unfortunately it is not possible to include the faulty code here
(pretty convoluted I would say, and requires large data set).
PS2: David, your educational remark is well taken. Actually I did look
up the online help, but (of course ?) I never looked into total, because
not in my dreams had I thought it could be that simple.
