[SciPy-Dev] 2D histogram: request for plotting variable bin size
Sat Feb 2 03:53:28 CST 2013
From the matplotlib developers it was pointed out, that there is a
NonUniformImage which might be suite for representing interpolated
variable bin size 2D histograms
There even exists an example
but it is very isolated and therefore not well known.
It would be very useful to explain its usage or at least link to it in
the histogram2d example at
In addition a pcolor example (attached below) shouldn't be missing. Even
though it is slow and can't do interpolation, it can at least do a
correct representation for academic purposes.
Can anybody do that or would you like me to do that myself?
import numpy as np, matplotlib.pyplot as plt
H, yedges, xedges = np.histogram2d(y,x, bins=(yedges,xedges))
extent = [xedges, xedges[-1], yedges[-1], yedges]
X,Y = np.meshgrid(xedges, yedges)
plt.pcolor(X, Y, H)
