You can transpose your inputs. For numpy arrays: x = x.transpo
Here is why the contours are wrong:
they are ploted verticaly, while I think, it is more common to draw temp.
contours in oceanography when the are horizontal.
Also, one more thing, I can't find how to expand the borders of the plot,
say from 350 to 400
(same for depth) I tried usig xlim and ylim(

Hi Eric,
really thanks for your help so far. I am doing a quick short course, and
I'll do the examples later.
I've fixed the code, here it is:
from matplotlib import pyplot as plt
temperature=[
[10,8,6],
[9,7,5],
[8,7,4]
]
distance = (100,200,300)

There are a couple of functions for loading ASCI

Thanks for the quick answer.
So if I have a series of 18 points withe measured distance, and 18 data

Hi,
I want to draw a contour plot which uses data from files. I know how to
import the files, so it's not the main issue.
Let's say I want to do a profile which has the following data:
distance, depth and some oceanographic data like temp, oxygen and stuff
so for simplicity lets say I have:

I've trying to install everything, from the begining on another machine,
this one's running openSUSE 10.3. So I've installed the latest versions
of numpy, scipy and matplotlib and I've discovered something new which
also happens in the first machine, the one with openSUSE 10.2. The fi
