OK, here is what I would do. I'd take about 3 or 4 really
deep breaths. Then maybe I'd go get a beer. While I was walking
to the cooler, I'd be thinking about what I was really
trying to do here.
When I got back, and finished the beer, I would re-read
all those Contour articles on Fanning's web page again,
this time with the goal of understanding why he is doing
the things he is doing.
Then, I would have a long, hard look at this code again.
Here are the questions I would be trying to ask myself.
(1) How many colors do I expect to see on the contour
plot? How do I know what those colors are? How do I know
if my data will be displayed with those colors? How can
I make sure it will be displayed with those colors? What
assumptions am I making currently that are just plain wrong?
When I worked though all of that, I'd write this code over
from scratch, making sure no line in it was longer than
about 50 characters or so, in case I had to send it to
somebody to help me with this. If I did need to send it,
I'd think about making a simple data set that I could send
them so they didn't have to spend a half hour themselves
writing code to run my program.
When I was finished with all of that, I probably wouldn't
have to ask any more questions, but if I did, I would be
in a MUCH better place to do so. :-)
Cheers,
David
