matplotlib-users Mailing List for matplotlib (Page 6)

Thanks so much for the tip. MPlot seems to be doing real-time plots
for me now, following a) your "-wthread" advice and b)having put the
measurement code in to a seperate thread. Does this seem unnecessarily
complicated? If it works under simpler circumstances, I'll let you know.

Also, the "-wthread" option seems to obviate the call to app.MainLoop().

Thanks again guys!

Recently the matplotlib data files have been moved into the matplotlib
module.  You should be able to safely remove share/matplotlib.

Done.

I have the same issue with py2app that is described with py2exe  
below. In order to work around this, I just needed to remove the  
"sys.platform=='win32' " check.

Could the developers please either:
Change the line to either:
	if (sys.platform=='win32' or sys.platform=='darwin') and sys.frozen:
or
	if sys.frozen:
Either is fine with me. I'm not sure how this affects linux/other  
*nix users, but they don't tend to freeze apps, so the second line is  
probably fine.

Regarding py2exe and zipping the python packages into a zip, (py2app  
also does this) does anyone have any troubles with freezing numpy and  
matplotlib? (This may be more relevant to the numpy list.) Numpy  
fails on import due to the pkgload() command trying to load the  
documentation. Everything works fine when I unzip the site- 
packages.zip into a site-packages directory, but I would prefer not  
to have to do this since it doubles the disk space my .app consumes.

Thanks,
Josh

 I am generating a few hundred graphs and doing so takes on the order of
about 10-15 minutes.  Which seems to me rather slow.  When I profile my cod=
e
it identifies the calls to  get_yticklabels and get_xticklabels as taking
over 90% of the time.  This seems strange but my calls to these functions
are merely a sort round about way of setting the font size of the axis tick
labels and suppressing the text for  the xticklabels.  Is there a more
efficient and cleaner way to do this?
      artist.setp(axes.get_yticklabels(), visible=3DTrue, fontsize=3D7)
      artist.setp(axes.get_xticklabels(), visible=3DFalse)


I am using matplotlib version 0.83.1 and the .png format for my output, if
that helps.  Though the profiler seems to suggest that the output is
blazingly fast and it is only these calls to the get_?ticklabels that are
slow.

Yes, I do have this working. I can package up numpy/scipy/matplotlib  
into a .app using py2app, and distribute it. The resulting package is  
rather large and only compresses to 9 MB, but I haven't yet looked  
into what I can exclude from the package or using the Apple-supplied  
Python to reduce size.

I've attached the MatplotlibView class that I made, using code from  
the matplotlib Cocoa backend. (I'm not using the mouse event  
interaction yet, so I haven't tested it.) Just insert a NSView into  
your nib file and set the custom class to MatplotlibView. Then add  
the view as an outlet in your app delegate. (this is "imageView" in  
the following code.)

What I then do in my app delegate is first create the initial look.  
It ends up like this:

     def applicationDidFinishLaunching_(self, notification):
         self.imageView.figure.set_facecolor('w')
         self.imageView.axes.set_axis_off()
         self.imageView.updatePlot()

And then in response to user events, I have a function that updates  
the view:

     def showImage(self):
         axes = self.imageView.axes
         axes.clear()
	...
         if self.displayimage is 'original':
             axes.imshow(self.fullcolourimage, extent=[0,imsizex, 
0,imsizey])
	...
         axes.set_axis_off()
         axes.set_xticks([])
         axes.set_yticks([])

         axes.set_xlim(0, imsizex)
         axes.set_ylim(0, imsizey)
         axes.set_aspect(aspect='equal')

         self.imageView.figure.subplots_adjust 
(left=0,right=1,bottom=0,top=1)
         self.imageView.figure.set_facecolor('w')

         self.imageView.updatePlot()

This will now work fine as long as your app is created using  
"setup.py py2app --alias".
There are a few problems when you want to distribute it and just use  
the standalone "setup.py py2app".

First, in your setup.py you will need to include the matplotlib data  
files:

import matplotlib, glob
mpldata = ''.join([matplotlib.rcParams['datapath'], r'/*'])
matplotlibdata = glob.glob(mpldata)
setup_options['data_files'].append((u'matplotlibdata', matplotlibdata))

This will include the files in your application bundle. When the mpl- 
data directory was moved, the code that allowed any data directory to  
be used was commented out. I am not sure, but I think it applied to  
win32 only anyway. So what you need to do next is edit the matplotlib  
__init__.py, find the lines below "CODE ADDED TO SUPPORT PY2EXE", and  
uncomment them. Remove the "if sys.platorm == 'win32'" (or similar)  
condition as well, to give:

     if sys.frozen:  ### Remove "sys.platform == 'win32' and" from here
         path = os.path.join(os.path.split(sys.path[0])[0],  
'matplotlibdata')
         if os.path.isdir(path):  return path
         else:
             # Try again assuming sys.path[0] is a dir not a exe
             path = os.path.join(sys.path[0], 'matplotlibdata')
             if os.path.isdir(path): return path

There also seems to be a problem with the way numpy/scipy handles  
being frozen, so you need to actually expand the site-packages.zip  
into a site-packages directory in the same location (and then remove  
the zip). Eg:

unzip -q build/XXX.app/Contents/Resources/Python/site-packages.zip -d  
build/XXX.app/Contents/Resources/Python/site-packages
rm build/Bovillator.app/Contents/Resources/Python/site-packages.zip

And you are done! This should help with you embedding matplotlib into  
an application. I have also developed a mixin class that lets you  
easily add Cocoa bindings to Python code with only one line of code.  
If you want it let me know.

I am also posting this to the matplotlib user mailing list. Since  
these problem issues also might affect others, I will post a shorter  
version detailing these to matplotlib devel and numpy mailing lists.

Cheers,
Josh

Hi

I'm trying to build 0.86.2 on my Debian box. I changed nothing in 
setup.py that came with the src tar.gz.

	python setup.py build

runs fine but

	sudo python setup.py install

gives

elcorto@ramrod:~/Install/Matplotlib/matplotlib-0.86.2$ sudo python 
setup.py install

I found that the pygtk and Tk related messages are produced by 
try/except clauses which try to import gtk and Tkinter, which works in

Any hints are appreciated. Many thanks.

ipython is only clever if you launch it in ipython -pylab for pylab
mode (which is not compatible with MPlot) or if launched in the
--wthread mode for wx threading.  So you'll definitely need to do the
latter.  I haven't had a lot of experience with --wthread; is it
correct that if you use wthread you should not use the explicit call
to Mainloop?

Hello again,

Here's a small chunk of code that exhibits the same problem I referred
to in an eariler email, ie it
won't repaint the window after an event has occured on it until the
code is complete.=20

frame.plot(rand(100),rand(100))

for i in range(15):
    frame.oplot(rand(100),rand(100))
    time.sleep(1)

NB The absence of an "app.MainLoop()" call at the end,
since I've called this from ipython, which is supposed to be clever and
automatically the wxPython main loop in another thread automatically (I
read this somewhere). I've tried running multi-threaded stuff from the
regular python shell, but without success.

Any ideas on how to get such a window to at least repaint in spite of
events on it, during replot commands?

Thanks in advance :-)

gridlines are part of the Axis, and do not obey the zorder.  But you
can put them above or below by setting the axisbelow property of the
Axes

  ax.set_axisbelow(True)

Dear Lisa,

thank you for your response to my problem getting started with matplotlib. As 
I reported already, the problem was a split up of the necessary python 
modules into two packages (namely, python2.3-numeric and 
python2.3-numeric-ext) in Debian Sarge, and I installed only 
python2.3-numeric.
However, having python packages in /usr/lib and /usr/local/lib should not be a 
problem, and is not a problem here.

Yours sincerely

If I'm not mistaken, zorder determines what objects will
be "on top" of what other objects.

I got this working fine for some lines on my plot but
it seems to have no effect on **grid lines**.
(I want grid lines to be *behind* everything.)

Here is code snippet for grid stuff....

        plot_.grid(True)
        grid_ =3D plot_.get_xgridlines() + plot_.get_ygridlines()
        pylab.setp(grid_, linestyle =3D "-", color =3D "k",=20
                   linewidth =3D "0.5",

I believe your problem is because your Numeric and numarray packages are no=
t
in the same directory as your matplotlib.  your matplotlib is in
/usr/local/lib and your numeric packages are in /usr/lib/.

if you install your packages all the same place, either /usr/ or /usr/local=
,
then it should work.  otherwise, there is some environment variable you can
set to tell everything where to look.  or the ugly way is to just symlink
what you need into the appropriate directories.

good luck.

i just installed matplotlib and all the requisite dependencies, and it seem=
s
to be running fine, except that show() is hanging and i'm not getting a GUI
plot.

I'm using the GTKAgg backend, which was automatically chosen by
setup.pywith the 'auto' flag.  i am able to save figures and all that,
but show()
just hangs at gtk.main().  i'm not sure why.  i ran the example
simple_plot.py with a --verbose-helpful flag and this is my output:

At one time, someone included some support in backend_ps.print_figure for 
passing a file object rather than a file name. For a file object, 
print_figure just appends to the existing file. I dont know how to use this 
properly, passing a file object to savefig raises an error.

Oh yes, this is an idea. Could have been mine ...

Hi,

Currently I'm using matplotlib on a machine to quickly evaluate whether 
certain settings for a measurement are good or not - as you all know 
graphical output helps. Now, I would like to dump all output in a single post 
script (ps or eps) file and browse through it using ghost view.

To facilitate getting some overview it would be ideal to be able to insert 
page breaks after each figure. Is this somehow possible with matplotlib 
(using the pylab interface)? (To be honest, I don't really expect this. But 
mpl had so many (for me) hidden features in the past, that I wouldn't be 
really surprised ;-). So I thought, I better ask, although I didn't find 
anything about it in the docs.)

TIA
Christian

Hello Nils,

I found the reason for the error message - in Debian python2.3-numeric is not 
enough, python2.3-numeric-ext is also required for matplotlib to work.

Sorry for bothering you, thanks for trying to help me!

Yours sincerely

Dear readers of this list,

I compiled and installed matplotlib-0.86.2 on a Debian Sarge GNU/Linux system. 
I can run some examples, e.g. agg_test.py or glyph_to_path.py, however, most 
examples end with an error message like this:

tobias@phoebus:~/matplotlib-0.86.2/examples$ python simple_plot.py
Traceback (most recent call last):
  File "simple_plot.py", line 6, in ?
    from pylab import *
  File "/usr/local/lib/python2.3/site-packages/pylab.py", line 1, in ?
    from matplotlib.pylab import *
  File "/usr/local/lib/python2.3/site-packages/matplotlib/pylab.py", line 195, 
in ?
    import cm
  File "/usr/local/lib/python2.3/site-packages/matplotlib/cm.py", line 5, in ?
    import colors
  File "/usr/local/lib/python2.3/site-packages/matplotlib/colors.py", line 33, 
in ?
    from numerix import array, arange, take, put, Float, Int, where, \
  File 
"/usr/local/lib/python2.3/site-packages/matplotlib/numerix/__init__.py", line 
62, in ?
    from Matrix import Matrix
ImportError: No module named Matrix

I reinstalled matplotlib according to the matplotlib-FAQ and tested again and 
got the same error message. I also changed in ~./matplotlib/matplotlibrc 
numerix from Numeric to numpy or numarray, but I got similar error messages.
I have python2.3-numeric and python2.3-numarray installed 
under /usr/lib/python2.3/site-packages/Numeric 
and /usr/lib/python2.3/site-packages/numarray, respectively.

What do I have to do to get matplotlib running?

Thanks for helpful hints in advance!

Yours sincerely
