Understood. And, yes, I guess you're quite right in this regard.
And I'll try to deprecate the current matlab-like interface in future

Hi all,
I had a few off-list conversation with Alan, and I'm also quite agree
with him for this issue.
Just to rephrase, I think the current subplot interface has (at least)
two issues.
issue 1) the indexing convention is not that of python. The index
starts from 1, instead of 0. (eg "111")

Hi mpl-users,
I have a web application in which I produce png files using
matplotlib. Unfortunately the files are quite big (up to ~300 kb). I
have however tried using the Linux tool pngnq to reduce the file size
with a factor ~3-4 with almost no degradation of the result. I
therefore wondered whe

My point is that that is not well defined,
since most of the OO API in Matplotlib is
Python centric, but the subplot definition
is an exception.
So I am suggesting that any new functions

Gökhan,
The "whos" command works for me.

Again, this means what it says.
Your data array is the wrong size.
You cannot for example reshape a (3,) array into a (2,2) array.

Hi Alan,
Thanks and it works for y and x but i guess i dont know how to shapet Z
("total size of new array must be unchanged")
Overall i just dont get it how to calcuate the nlons and nlats fro Z.
yre = np.reshape(lats,nlats)
xre = np.reshape(lons,nlons)
print yre
print xre
zre = np.resh

Listen to Python: all the info is there.
A list is not a numpy array.
Don't treat it like one.
However you can do:
numpy.reshape(mylist, myshape)

Why dont anyone answer me???
atlest give me a hint...
Ok, so i want to use the my csv as input and then plot the contour. I have
the follwing code but gives

is using list diffrent than using numpys loadtext and then into variables

João,
Thank you for commenting on the code. sys.argv check is a wise one. Since I
was the only user of this little snippet I didn't give attention of this
detail, however eventually some other people will start using the code too.
I thought it is more efficient to only import functions that I use
