I start using matplotlib a month ago, so I'm still learning.
I'm trying to do a heatmap with matshow. My code is the following:
data = numpy.array(a).reshape(4, 4)
cax = ax.matshow(data, interpolation='nearest', cmap=cm.get_cmap('PuBu'), norm=LogNorm())
cbar = fig.colorbar(cax)
ax.set_xticklabels(alpha)
ax.set_yticklabels(alpha)
where alpha is a model from django with 4fields: 'ABC', 'DEF', 'GHI', 'JKL'
the thing is that I don't know why, the label 'ABC' doesn't appear, leaving the last cell without label.
If someone would have a clue how to modify my script in a way to appear the 'ABC' I would be grateful :)
