Hi,
When histogramming integer data, is there an easy way to tell matplotlib
that I want a certain number of bins, and each bin to cover an equal number
of integers (except possibly the last one)? (in order to avoid having some
bins higher than others merely because they cover more integers)
I know I can pass in an explicit bins array (something like list(range(min,
max, (max-min)//n)) + max) but I was hoping for something simpler, like
hist(data, nbins=42, equal_integer_coverage=True).
Best,
Antony

Hi,
I am using Basemap to create a grid of 12 images of the world (months of
the year), but I want to have a single colorbar underneath the plots. I
have managed this successfully but I can't manage to shrink the colorbar
width. Currently it extends the entire width of the plotting window,
whereas I'd prefer it to be say extend 80% of the plotting window. I've
tried combining what I have with the shrink argument to colorbar but this
doesn't work. Does anyone know how I can achieve this?
Code:
import numpy as np
import matplotlib.pyplot as plt
import sys
import matplotlib.colors as colors
from mpl_toolkits.basemap import Basemap
from mpl_toolkits.axes_grid1 import AxesGrid
months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct',\
 'Nov','Dec']
fig = plt.figure(figsize=(14, 10))
grid = AxesGrid(fig, [0.05,0.05,0.9,0.9], nrows_ncols=(4,3), axes_pad=0.1,
 cbar_mode='single', cbar_pad=0.4, cbar_size="7%",
 cbar_location='bottom', share_all=True)
m = Basemap(projection='cyl', llcrnrlon=-179.5, llcrnrlat=-59.5, \
 urcrnrlon=179.5, urcrnrlat=89.5, resolution='c')
for i, month in enumerate(months):
 ax = grid[i]
 m.ax = ax
 m.drawcoastlines(linewidth=0.1, color='k')
 m.drawcountries(linewidth=0.1, color='k')
 if i == 0 or i == 3 or i == 6 or i == 9:
 m.drawparallels(np.array([-90.0,-60.0,-30.0,0.0,30.0,60.0,90.0]),
 labels=[1,0,0,1], fontsize=10, rotation=0,
 linewidth=0.2, dashes=[2,2])
 else:
 m.drawparallels(np.array([-90.0,-60.0,-30.0,0.0,30.0,60.0,90.0]),
 labels=[0,0,0,0], fontsize=10, rotation=0,
 linewidth=0.2, dashes=[2,2])
 if i >= 9:
m.drawmeridians(np.array([-180.0,-120.0,-60.0,0.0,60.0,120.0,180.0]),
 labels=[0,0,0,1], fontsize=10, rotation=00,
 linewidth=0.2, dashes=[2,2])
 else:
m.drawmeridians(np.array([-180.0,-120.0,-60.0,0.0,60.0,120.0,180.0]),
 labels=[0,0,0,0], fontsize=10, rotation=00,
 linewidth=0.2, dashes=[2,2])
 diff = np.random.rand(150,360)
 image = m.imshow(diff, cmap=plt.cm.jet, interpolation='nearest')
 textstr='%s' % (month)
 props = dict(boxstyle='round', facecolor='white', alpha=1.0, ec="white")
 ax.text(0.03, 0.1, textstr, transform=ax.transAxes, fontsize=8,
 verticalalignment='top', bbox=props)
cbar = fig.colorbar(image, cax=grid.cbar_axes[0], orientation='horizontal')
plt.show()
Thanks,
Martin

Dear Christoph Gohlke Thanks, now working. Best regards Robert

Try unbundling the Python interpreter using the `'bundle_files': 2` 
option <http://www.py2exe.org/index.cgi/SingleFileExecutable>. Works for 
me with Python 3.4 (2.7 works with `'bundle_files': 3`).

I need to embedding matplotlib in pyqt4, i use the below code in my project:
from matplotlib.backends.backend_qt4agg \  import FigureCanvasQTAgg as FigureCanvas
convert to exe with py2exe, however running exe i got the error:
 File "matplotlib\backends\backend_qt4agg.pyo", line 19, in <module> File "ctypes\__init__.pyo", line 378, in __getattr__ File "ctypes\__init__.pyo", line 383, in __getitem__AttributeError: function 'Py_DecRef' not found
environment in my pc:python2.7PyQt GPL v4.10.3 for Python v2.7 (x32)
Thanks
