So my beginner saga continues with another question:
I am trying to create a custom colormap using ListedColormap. The custom

file is between 0 and 8. Now my issue is that when plotting the graph the
colormap is using the 0 t

I've got it sorted out a bit now. You're right the data was an output from
Degrib and I had the option to output the csv's with or without data in the
land areas. As before I was using a program that was placing the pixels in
an image based on the X and Y columns it didn't create an iss

It seems that I just cannot grasp the way the data needs to be formatted for
this to work...
I've used the griddata sample that James posted but it takes about 10
minutes to prep the data for plotting so that solution seems to be out of
discussion.
I guess my issue is that I don't know what type

Here is a short recipe:
Is there a PyNIO binary for windows as on their download page there are only
Linux, Mac or Solaris versions?

that it's a 33mb file:

Here is the link to the folder that has the grib files. They are updated
every 3 hours:
ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/wave/prod/
Any of the files there would have the same info only at different times of

Scott, the Scatter function works great but i am really looking to use the
contourf one.

looked at the griddata example and here is the code I came up with:

Hi all,
I am pretty new to matplotlib and I have a big issue... I am trying to plot
data from a grib file from noaa and I am not sure what's the best way to go
about it. Until now, I am extracting the data i need in CSV files but I am
