Re: [Matplotlib-users] cxfreeze
I managed to resolve it, by following Mike's hint thanks Mike.
It was simply to change the setup.py script to
import cx_Freeze
import sys
import matplotlib
base = None
if sys.platform == win32:
base = Win32GUI
executables = [
cx_Freeze.Executable(script.py, base = base)
]
cx_Freeze.setup(
name = script,
options = {build_exe: {include_files:[(
matplotlib.get_data_path(),mpl-data)],}},
version = 0.1,
description = Sample matplotlib script,
executables = executables)

I have no experience with cx_freeze, but the page on packaging
matplotlib with py2exe may be relevant. You do need to find a way to
convince cx_freeze to include the data files and then a way for
matplotlib to find them at run time.

Hi,
I want to build executables from python scripts that call matplotlib
under linux. To this end I have installed cxfreeze on my SuSE 11.2
machine
I have tried two methods
1. Execute the command 'cxfreeze script.py'
and
2. Creating a setup.py script
import cx_Freeze
import sys
base = None
if sys.platform == win32:
base = Win32GUI
executables = [
cx_Freeze.Executable(script.py, base = base)

cx_Freeze.setup(

version = 0.1,
description = Sample matplotlib script,
executables = executables)
and then execute 'python setup.py build'
In both cases I get an executable, but when executed I get the following
error RuntimeError: Could not find the matplotlib data files
The version of matplotlib I am running is 0.99.1.1 and Python 2.6.2
Does anyone have any thoughts/suggestions to resolve this, thanks

[Matplotlib-users] Overlapping labels in pie charts
Hello, I am having some issues generating pie charts, when some of the slices become very small, their labels will draw on top of each other, making it impossible to distinguish between them. And I am trying to avoid using a legend. Does anyone know if there is a way to properly position labels of pie charts to avoid overlapping.

Re: [Matplotlib-users] Sharing axes on multiple subplots

Hello,
I wrote the solution implemented in the hope that it serves at someone else.
The Situation
=
I wrote a script using basemap and matplolib. which draw a map.Dread a
file containing a bunch of Genbank accession numbers, and downloaded
the Genbank records:
from pylab import *
import os, sys
import os.path
from mpl_toolkits.basemap import Basemap
import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties
map = Basemap(projection='cyl', resolution='l')
map.drawcoastlines()
map.drawmapboundary()
...
This worked fine as a script, but when I attempted to turn it into a
Windows executable with py2exe and the setup.py script:
from distutils.core import setup
import py2exe
from distutils.core import setup
import py2exe
import glob
import matplotlib
opts = {
'py2exe': { includes : [sip, PyQt4, matplotlib.backends,
matplotlib.backends.backend_qt4agg,
matplotlib.figure,pylab, numpy,
matplotlib.numerix.fft,mpl_toolkits.basemap,
matplotlib.numerix.linear_algebra,
matplotlib.numerix.random_array,
matplotlib.backends.backend_tkagg],
# 'excludes': ['_gtkagg', '_tkagg','_agg2','_cairo',
'_cocoaagg', '_fltkagg', '_gtk', '_gtkcairo', ],
'dll_excludes': ['libgdk-win32-2.0-0.dll',
'libgobject-2.0-0.dll']
}
}
data_files = [(r'mpl-data',
glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\*.*')),
# Because matplotlibrc does not have an extension,
glob does not find it (at least I think that's why)
# So add it manually here:
(r'mpl-data',
[r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\matplotlibrc']),
(r'mpl-data\images',glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\images\*.*')),
(r'mpl-data\fonts',glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\fonts\*.*'))]
setup(windows=[{script : myapp.py,
icon_resources: [(1, myapp.ico)]}, ],
version = 1.0,
options=opts, data_files=data_files)
with the command python setup.py py2exe, attempting to run the
resulting myapp.exe would throw an error.
The Error
This is the error thrown on running the executable:
Traceback (most recent call last)
File myapp.py, line 40, in module
File mpl_toolkits\basemap\__init__.pyc, line 774, in __init__
File mpl_toolkits\basemap\__init__.pyc, line 848, in _readboundarydata
IOError: Unable to open boundary dataset file. Only the 'crude', 'low',
'intermediate' and 'high' resolution datasets are installed by default.
If you are requesting a 'full' resolution dataset, you may need to
download and install those files separately
(see the basemap README for details).
The Problem
==
Location of basemap data
The problem is identified when basemap is imported, the code of
basemap/__init__.py try to establish the basemap data directory in the
library.zip file.
[install dir]\dist\library.zip\mpl_toolkits\basemap\data
Under normal script-like execution, it works, the path is a string
indicating a location accessible through the filesystem . However with
py2exe, the location of data basemap directory is located within the
shared zip archive that py2exe creates and the above error is thrown.
The Solution
==
The solution came in three times
1. Add mpl_toolkits.basemap in the option list (setup.py)
#
opts = {
'py2exe': { includes : [sip, PyQt4, matplotlib.backends,
matplotlib.backends.backend_qt4agg,
matplotlib.figure,pylab, numpy,
matplotlib.numerix.fft,mpl_toolkits.basemap,
matplotlib.numerix.linear_algebra,
matplotlib.numerix.random_array,
matplotlib.backends.backend_tkagg],
#
2. Add basemap\data in data_files list
#
data_files = [(r'mpl-data',
glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\*.*')),
(r'mpl-data',
[r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\matplotlibrc']),
(r'mpl-data\images',glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\images\*.*')),
(r'mpl-data\data',glob.glob(r'C:\Python25\Lib\site-packages\mpl_toolkits\basemap\data\*.*')),

I've been trying to modify the embedding_in_tk.py example to use the

recently).

TopLevel() command. I switched this to Tk.Tk() and it works nicely.
However I still have to pack the frame instead of using grid. I can
work around this but I wonder if there isn't something else I'm
missing.

I've been trying to modify the embedding_in_tk.py example to use the
grid manager instead of pack. I can get the plot to show ok but I
can't seem to get the toolbar to show correctly. The following code
does get the toolbar on there but it does use pack for the frame and
also I always end up with an extra blank window (this code is
simplified from something that a Bonnie Douglas posted on this list
recently).
Any suggestions?
#!/usr/bin/env python
import matplotlib
matplotlib.use('TkAgg')
import Tkinter as Tk
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg,
NavigationToolbar2TkAgg
from matplotlib.figure import Figure
from numpy import arange, sin, pi
# create toplevel window
tl=Tk.Toplevel()
tl.title(storage)
# create frame
frame=Tk.Frame(master=tl)
fig=Figure(figsize=(12,6), dpi=100)
# create plots
a1 = fig.add_subplot(111)
t = arange(0.0,3.0,0.01)
s = sin(2*pi*t)
a1.plot(t,s)
# create canvas
canvas=FigureCanvasTkAgg(figure=fig, master=frame)
canvas.show()
c=canvas.get_tk_widget()
c.grid(row=0, column=0)
# problems with toolbar not showing solved by setting the master to
# the toplevel window, not the frame!!!
toolbar=NavigationToolbar2TkAgg(canvas, tl)
toolbar.update()
frame.pack()
Tk.mainloop()
