matplotlib-users Mailing List for matplotlib

Thank You Scott,
                I mistook the values  I assumed .1 to .8 as the total x size and expected half of it should provide me 2 half boxes.
thanks a lot for clarification.
with best regards,
Sudheer

You don't say exactly what you did, and how it didn't work...

If you read http://matplotlib.org/api/figure_api.html?highlight=add_axes#matplotlib.figure.Figure.add_axes
it says "Add an axes at position rect [left, bottom, width,
height]...". So you need to specify sensible values in rect1 and
rect2.

The following works fine for me:

import matplotlib.pyplot as plt
fig = plt.figure()
rect1 = [0.1, 0.1, 0.4, 0.4]
rect2 = [0.55, 0.1, 0.4, 0.4]
ax1 = fig.add_axes(rect1)
ax2 = fig.add_axes(rect2)
ax1.plot(range(3))
ax2.plot(range(4, 8))
plt.show()

So I would expect that you can adapt your original code to something
like the following (untested):

from windrose import WindroseAxes
from matplotlib import pyplot as plt
from numpy.random import random

def new_axes(fig, rect):
    ax = WindroseAxes(fig, rect, axisbg='w')
    fig.add_axes(ax)
    return ax

def set_legend(ax):
    l = ax.legend(axespad=-0.10)
    plt.setp(l.get_texts(), fontsize=8)

#Create wind speed and direction variables
ws = random(500)*6
wd = random(500)*360
ws1 = random(500)*6
wd1 = random(500)*360

rect1 = [0.1, 0.1, 0.4, 0.4]
rect2 = [0.55, 0.1, 0.4, 0.4]

fig = plt.figure(figsize=(8, 8), dpi=80, facecolor='w', edgecolor='w')

ax1 = new_axes(fig, rect1)
ax2 = new_axes(fig, rect2)

#windrose like a stacked histogram with normed (displayed in percent) results
ax1.bar(wd, ws, normed=True, opening=0.8, edgecolor='white')
set_legend(ax1)

#windrose like a stacked histogram with normed (displayed in percent) results
ax2.bar(wd1, ws1, normed=True, opening=0.8, edgecolor='white')
set_legend(ax2)

plt.show()

Cheers,
Scott

Thanks Derek & John.

Very strange. Here's my setup:

>>> import matplotlib
>>> matplotlib.__version__
'1.2.0'
>>> matplotlib.get_backend()
'TkAgg'


Would you mind providing all of the relevant details suggested in
http://matplotlib.org/faq/troubleshooting_faq.html#troubleshooting, along
with the code to reproduce the problem in a new github issue?

Once I have all of the necessary details, I'd be happy to have a look into
this to see if I can find a solution.

Cheers,

Phil

Thank you Scott,

Some how I am not getting the trick of the 
rect = [0.1, 0.1, 0.8, 0.8]

I tried 
rect1= [0.1,0.1,.4,.4]
and rect2=[.4,.4,.8,.8] 
but did not work

Derek,

I just tried Phil's version of the code on my Mac (MP 1.2.0), and I  
see exactly the same problem as in your grab.tiff. This is using the  
default TkAgg backend.

I happen to have built MP 1.2.0 with the Qt4 backend option. When I  
prepend the lines

     from matplotlib import use
     use("QT4Agg")

to use Qt4, I get the expected (correct) display output.

Apparently this is a bug somewhere in the chain TkAgg/Tkinter/Tk.

John
