I tried directly the setup.py, it does not work with wxcursor_demo.py
My first try was=A0 modifying the following in the setup.py :
#mpldata =3D glob.glob(r'C:\Python24\share\matplotlib\*')
mpldata=3D[]
 for di in allsubdirs(r'C:\Python24\Lib\site-packages\matplotlib'):
=A0=A0=A0 ti=3Ddi+'*.py*'
=A0=A0=A0 mpldata=3Dmpldata+glob.glob(ti)
#mpldata.append(r'C:\Python24\share\matplotlib\.matplotlibrc')
mpldata.append (r'C:
\Python24\Lib\site-packages\matplotlib\mpl-data\matplotlibrc')
The exe fails at importation line :
from matplotlib.numerix import arange, sin, pi
Here is the error log :
Traceback (most recent call last):=20
=A0 File "wxcursor_demo.py", line 7, in ?
=A0 File "zipextimporter.pyo", line 82, in load_module
=A0 File "matplotlib\__init__.pyo", line 720, in ?
=A0 File "matplotlib\__init__.pyo", line 273, in wrapper=20
=A0 File "matplotlib\__init__.pyo", line 360, in _get_data_path
RuntimeError: Could not find the matplotlib data files
So I guess I did quite wrong! I have too look further...
BTW, I'm using enthon-python2.4-1.0.0.exe

Hi,
I have plotted my data (x,y) to line plot without axis
adjustments right. But if I scale y axis (with 'axis')
and cut some maximal values of y data out, it seems
that y is drawn within new margins of y axis, but just
translated some way. (small graphs PNG attached). PNG
made with savefig has different "zig-zags". My graphs
SHOULD NOT have any data line x(0-3.4). It makes no
problem if I scale x axis. My script:
import pylab as P
 
P.plot(x, y, 'k-', label='Total', linewidth='2')
P.axis([0.0,15,-0.4,0.5])
P.xlabel('Distance, A')
P.ylabel('Energy')
P.grid(True)
P.savefig('scatter_demo',dpi=150)
P.show()
Arturas
P.S. MS XP / python 2.4 / matplotlib-0.87.7

Deat Matplotlib Users,
I have to plot the frequency response of many filters on one
plot, and have to take a printout, necessarily black and white. Now, I
would like to use symbols at frequent intervals as well, for easy
distinguishing. Now, I wanted to know whether it is possible to have
the legend show both the line and the type of dot (such as square and
dotted line, circle and dot-dash) on a _single_ legend entry. Though I
am able to show the symbol in the legend, it would be nice to have
both shown as a single entry.
Thanks.
Kumar

I had a quick look and for the first part of the second question:
> (a) what is the syntax for the fill() command - I have tried
> ax.fill(0.5,0.5,'b') and get an error:
> TypeError: zip argument #1 must support iteration
The TypeError is saying that the argument expected should be a Python 
type supporting iteration, such as a numpy array, a list or a tuple. 
i.e. this produces a rectangle:
ax.fill([1,1,2,2],[3,4,4,3],'b')
where the two lists contain the x- and y-coordinate polygon vertices, 
respectively, ordered clockwise from the lower left.
It would take me a bit of mucking around to work out what the bar 
coordinates are - hopefully an expert will pipe in with the answer. You 
probably need to work out how to apply the get_verts method to the patch 
collection. I find using ipython interactively is the best way to learn 
to do this.

Hi,
I want to import binary files generated from C/FORTRAN into matplotlib for
plotting. 
Can this be done using 'load'?
Thanks

Importing matplotlib I get the warning message
/usr/local/gltools/python/Python-2.5/linux/lib/python2.5/site-packages/matplotlib-0.87.7-py2.5-linux-i686.egg/matplotlib/__init__.py:155: UserWarning: Module matplotlib was already imported from /usr/local/gltools/python/Python-2.5/linux/lib/python2.5/site-packages/matplotlib-0.87.7-py2.5-linux-i686.egg/matplotlib/__init__.pyc, but /usr/software/gltools/python/Python-2.5/lib/python2.5/site-packages/basemap-0.9.4-py2.5-linux-i686.egg is being added to sys.path
 __import__('pkg_resources').declare_namespace(__name__)
The directory '/usr/local/gltools' is a symlink to
'/usr/software/gltools' so adding the second directory. What is
responsible for this message, an can anything be done about it?
Kind Regards
Berthold

Hi
 
I appreciate that this is a totally voluntary support list, but
I was wondering what the protocol was when queries that
I have posted go unanswered...
 
Should I -
(a) repost them "as is"?
(b) rewrite them slightly and post them again
(c) assume no one has any interest in answering them (and give up)
(d) something else??
 
The queries I am referring to are:
http://sourceforge.net/mailarchive/message.php?msg_id=38032560 
and
http://sourceforge.net/mailarchive/message.php?msg_id=38021694 
 
(The latter especially, I am sure is within matplotlib current
capabilities... and a hint or two will set me on the right track!)
 
Thanks
Derek

Dears,
I succeeded embedding figure, plot, hist and bar into PyQt3 and PyQt4 wi=
th the suggestion of the examples.
But I don't see anywhere how I can do the same thing for the 3D plots.
Does anyone have some idea or piece of code?
Many thanks
Olivier

I am way behind on matplotlib version (still on 0.82) but here is an=20
example setup.py to freeze the matplotlib sample wxcursor_demo.py=20
(included just in case it changed).
I just have no time yet to upgrade to a newer version, especially as I=20
want to upgrade to wxPython 2.8 at the same time.
Here a fews things I recall from my tests with 0.87.3:
- you need to use the unicode build of wxPython (also this might have or=20
will change).
- matplotlib data folder handling (see in setup.py commented line in=20
data_files section)
- numpy (just tried it building against 87.3 but get errors related to=20
numpy, one probably has to force more inclusions)
Hope this helps
Werner
