[Matplotlib-users] images from data

[Michael V. De P. <mde...@ma...>]

Hi all,

I am trying to use imshow to plot an image from some data. Basically,
I have a list of x, y, and z values, and I want to plot z as a
function of x and y.

Unfortunately, most of the  examples do this as far as I can
tell. Instead, they (at most) take a list of x and y then make a
*function* z out of that, and plot z, rather than having actual data
from a file for all three.

The only one that does seem to do something like this seems to be
dependent on a binary file, which unfortunately is not the format I
have the data in. Sure, I could convert the very large files I already
have into binary, but in the long run, I think it would be better for
me to be able to simply use the ASCII data that I am provided with
since that can't be changed.

Is there an easy way to do this, or will I just have to convert the
files?

Thanks,

Mike
