as someone suggested, you really want to read up on numpy -- the 
transpose method is a method of numpy arrays. numpy arrays are kind of 
like Matlab matrixes, only more powerful and flexible. MPL is using 
numpy arrays inside anyway.

if you have a contour plot,  you have depth,distance as your x,y 
coordinates, with the temp value shown by the contours  How did you 
expect to plot temp on top of that?

Either way, there is not choice but to learn a bit first! As hard as 
this is, you're right trying to do all your computation and plotting 
with with a spreadsheet is a nightmare -- you'll be glad you've learned it!

Have you read the MPL docs -- there's a lot of good, simple examples in 
there:
