Would you please consider licensing this project to an Open Software Initiative or Free Software Foundation approved license that fits the motivations of this project?

Personally, I think a CC0 License fits this project well but this is very much a decision for the original authors.

Why?

I'd like to use this.

Hi @jobar8

I am trying to use your (fantastic) graphics.py, but I've been facing a strange behavior that I cannot explain or, worse, solve.

I tried imshow_hs with 3 different data sets, but there is one that always crashes the code when hs=True, i.e. shading is on.

At some point, I believed that it was a matplotlib issue, so I started a Jupyter Notebook to do a bug report. Turns out that I don't know now the origin of the problem, so I thought to ask your help.

Below is the code that works with your dataset (mag4017) and then crashes with mine. Same input parameters.
Dataset that works → mag4017
Dataset that does not work → my_data

import numpy as np
import matplotlib.pyplot as plt
import graphics

data_good = np.load('mag4017.npy')
fig,ax = plt.subplots(figsize=(12,6))
graphics.imshow_hs(data_good,ax,cmap=plt.cm.gist_earth,cmap_norm='equalize',hs=True,zf=2,levels=32,colorbar=False,
                   cb_ticks='stats',nSigma=2,azdeg=45,altdeg=45,blend_mode='overlay',alpha=0.7,
                   extent=extent, origin='lower')

data_bad = np.load('my_data.npy')
fig,ax = plt.subplots(figsize=(12,6))
graphics.imshow_hs(data_bad,ax,cmap=plt.cm.gist_earth,cmap_norm='equalize',hs=True,zf=2,levels=32,colorbar=False,
                   cb_ticks='stats',nSigma=2,azdeg=45,altdeg=45,blend_mode='overlay',alpha=0.7,
                   extent=extent, origin='lower')

It doesn't matter if you choose blend_mode=alpha or whatever.

In the file attached, there is a Jupyter Notebook that also shows a function that I did to try to "mimic" the problem, but it runs well where graphics.py crashes.

To sum up, I am waaayyyyy lost!

I've been using your fantastic imshow_hs function. I recently upgraded to matplotlib2.0 and now when I run a script using imshow_hs it crashes python. I've reverted back to matplotlib 1.5.3 which fixes the problem. Have you tried this one matplotlib2.0?
Thanks
