Hi everybody,

About two weeks ago I was asking on this mailing list if matplotlib can make hexagonal binning plots as an alternative to scatter plots. I have now written such a function for matplotlib. In case other people are also looking for this functionality, the patch is available here:

http://sourceforge.net/tracker/index.php?func=detail&aid=1952339&group_id=80706&atid=560722

As an example of this function, the two figures below show a traditional scatter plot, and a hexagonal binning plot using the same data:

Traditional scatter plot:

Hexagonal binning plot, using the same data:

Hi everybody,

Is there a function in matplotlib for hexagonal binning of scatter plots? Here are some examples of what I am looking for:

Michiel,

That looks very nice. I committed it to the trunk as svn 5084. Thank you!

Please provide a simple demo script suitable for inclusion in the examples subdirectory, and I will commit that also. I think it would be nice to have two subplots, one with a linear color scale, the other with a log scale, and with a colorbar for each. (There might be some wrinkles with colorbar for a log scale--I don't recall.)
