Well, now you can make them yourself :-)

  > make -f make.osx binaries

But we will try to get some official ones out in the near future.

Dear John and George,

I am happy to report that everything is now working!
The latest SVN patch fixed the fetch problem and a complete removal of
my custom compiled libpng and libfreetype2 followed by:

sudo make -f make.osx fetch deps mpl_build mpl_install
sudo python setup.py install

did the rest.

Thank you for all your help!

Kind regards,

Pim Schellart

P.S. I am looking forward to seeing 64 binaries for Python 2.6/2.7 and
numpy/scipy/matplotlib on OSX 10.6 at some point in the future :)

Brilliant, that worked perfectly!

Thanks very much,

today i produced an image that failed to save to eps. 
i can save the file in pdf, but i get the same error if i try to use
pdf2ps. png works too, but its not vector. 

not sure if its important, but the image has 401 lines, with 500 points
each.


the image is produced from a bunch of data files and im not sure how to
most effectively send this over email ( in case you all wanted to
re-produced the error).

the main error is 

Error: /nocurrentpoint in --lineto--

here is the whole error

thanks 
alex

Hi,
I am a real newbie at matplotlib, so I apologize if this is an obvious
question.
I am running ipython in emacs and while the first time I use the show()
command in the ipython buffer the graph shows up fine, subsequent times that
I call the command it, the graph does not show up. I am on ubuntu 10.04
(64) and I built the matplotlib library from source.
I am trying to get the graphs to show up the subsequent times as well (sorry
for the pun).
Thanks for any help.

You need to define your own transform. And the best way is to read
through the transforms.py. Here is a modified version of your example
that uses a custom transform.

However, often you may need to use a custom locator also for this kind
of transform.

HTH,

Looks like a bug in the makefile -- when un-tarring zlib, it should be
'tar xvfz' not 'tar xvfj'.  I was recently tinkering with bz bs gz
files and looks like the flags got out of whack.  I've patched this in
svn so you can 'svn up' and try again.

You could hack through make.osx to find your own libs.  We do it this
way to build distributable binaries where we can't count on targets
having the right png/freetype on their os x systems.  distutils is
limited as a configure system so it is difficult to hack this kind of
stuff into setup.py.  Not that what we are doing is ideal, but we have
been striving for "works" over "perfect".  The former is hard enough
on OS X.  Any improvements you can make to make this more general are
of course welcome.

May these pages help you?

Hi,

I've made a matplotlib plot with frequency  on the x-axis, and I would 
like to add an additional x-axis at the top that is measured in 
wavelength , i.e. wavelength = 3e8 / frequency

Is there anyway to do this transformation automatically in matplotlib?

I tried to give a transformation argument to the ax.twin() axes_grid 
command, as shown in the axes_grid parasite_simple2.py example,  but 
I've not managed to get this to work with a transformation more 
complicated than a scaling by a constant factor. I tried looking at the 
matplotlib.transforms documentation but I couldn't see a way to do this 
transformation there. I'm not sure I understood it very well though. I 
can't simply use the twiny( ) command and manually set the limits as the 
wavelength ticks will not occur at the points corresponding to the 
correct frequency.

At the moment I am using the twin() command, and then I  manually choose 
a sensible set of tickvalues  I want in wavelength units,  calculate the 
corresponding frequency values, and then set the tick locations to be 
the frequency values and the tick labels to be the wavelength values.

Thanks,
Sarah

Example code:
import numpy as np
import matplotlib
from mpl_toolkits.axes_grid1.parasite_axes import SubplotHost
import matplotlib.pyplot as plt
#create xaxis range of values -- 200 -- 1000 Ghz
xvals = np.arange(199.9, 999.9, 0.1)
#make some test data
data = np.sin(0.03*xvals)
#set up the figure
fig = plt.figure()
ax = SubplotHost(fig, 111)
fig.add_subplot(ax)
ax2 = ax.twin()
#plot data
ax.plot(xvals, data)
ax.set_xlim(200.0, 1000.0)
#set up ax2 with chosen values
wavelength_labels = np.array([0.4, 0.6, 0.8,1.0,1.2, 1.4]) #in mm
frequency_points = 3e2/wavelength_labels #in GHz
ax2.set_xticks(frequency_points)
ax2.set_xticklabels(wavelength_labels)
ax2.set_xlabel('Wavelength (mm)')
ax.set_xlabel('Frequency (GHz)')
plt.show()

Hi,

This is probably easy to do but I didn't work it out from the 
documentation so far. How do I remove the tick lines on a plot but keep 
the labels?

Thanks,
John.

Does anyone have an idea where the architecture error comes from, or
how to check this?

Could the same functionality not have been integrated into the setup.py script?
This is not a rant, just a question :)

Thank you.  The tutorial was very helpful.  For a moment I thought I might
have found the answer with the lines.remove() function but alas, it did not
make a difference yet again.  :(  I am starting to feel that this is a
problem with my setup rather than my code.  I may have to try this on
someone else's computer.

This is almost exactly the same as something else I have tried but this is

2) In which case, it's not a framework install.  Fink puts everything into
/sw/; there's nothing to do with pyton in /Library/Frameworks.
Thanks for the clarification; I'm tempted to get Python from source and try
this...

OK that is good to know.

This is important. Check where python is installed. If 'which python' shows /Library/Frameworks/Python.framework/Versions/2.6/bin/python or something similar, you have a framework version. If on the other hand it shows /usr/bin/python, /usr/local/bin/python, or something similar, you don't have a framework version. I don't know what fink installs by default. If you don't have Python installed as a framework, some backends (including the MacOSX backend) will not interact properly with the window manager. This is a Mac peculiarity. If you build Python from source, you can specify to install a framework version by passing the --enable-framework option to the configure script.

Some backends go make use of X11 (e.g., the gtkcairo backend), others do not (e.g., the MacOSX backend). The MacOSX backend should work with both the native Mac terminal and with an X11 terminal.

--Michiel.



      

Hi,
I am a real newbie at matplotlib, so I apologize if this is an obvious
question.
I am running ipython in emacs and while the first time I use the show()
command in the ipython buffer the graph shows up fine, subsequent times that
I call the command it, the graph does not show up.  I am on ubuntu 10.04
(64) and I built the matplotlib library from source.
I am trying to get the graphs to show up the subsequent times as well (sorry
for the pun).
Thanks for any help.

----------------------------------------

Thanks for the info...
1)The problem does manifest in the same manner through the normal python
prompt.
2) I'm not sure what is meant by a "framework install."  Everything (except
MPL 99.1.1) was installed through fink.
3) I've never had problems with Fink software before, and I have a crapload
(technical term) of stuff installed.  This is neither here nor there,
however, as it seems that not all Pythons are created equal.
4) A colleague of mine claims to have everything working on a new Intel mac
(I'm guessing 10.5.8) right out of MacPorts; I'll talk to him more and try
to find out what is different between our two cases.
5) I have yet to try installing wxPython for python 2.5; this may work in
the end.  It's not in fink, so I've put off installing it manually.  I'll
give it a shot and let you know how it works.
6) Although I use x11 and not the native Mac terminal, I'm not sure if this
requires me to install different packages for the gui stuff.  Could you guys
expand on this, please?

Finally, I've had some measure of success by installing Qt4 (through Fink)
and using the Qt4Agg backend.  Because the current stable fink Qt4 release
(4.6.1) has a bug, I need to apply the fix found here:
http://old.nabble.com/Qt4-backend:-critical-bug-with-PyQt4-v4.6%2B-td26205716.html
in order to allow more than one plot per session to be shown.  I'll re-write
the fix here for convenience and clarity (the original did not have the
proper module references in it, so this saves some 5 minutes of
tab-completion work in ipython...)

# Add this before "FigureManagerQT" class
class FigureWindow(QtGui.QMainWindow):
    def __init__(self):
        super(FigureWindow, self).__init__()
    def closeEvent(self, event):
        super(FigureWindow, self).closeEvent(event)
        if QtCore.PYQT_VERSION_STR.startswith('4.6'):
            self.emit(QtCore.SIGNAL('destroyed()'))
# Replace "QtGui.QMainWindow" by "FigureWindow" in
"FigureManagerQT"'s constructor

This works perfectly on my Intel machine running MPL 99.1.1.  It's fast and
looks sharp.  I'll report back on the PPC/99.0 combo tomorrow; Qt4 takes a
thousand hours to compile.

Thanks for the input.

Right, I am running Snow Leopard and have Python 2.6 installed 64 bit. 
Apparently, Carbon requires 32 bit and wxWidgets/wxPython does not (yet) 
support Cocoa.  This problem will bite you in one form or another on Mac 
OS X, regardless of whether you are using Macports or something else.

Not exactly true.  Fink and Macports are tools and have their 
shortcomings, but both can be immensely useful for installing all this 
stuff.  Otherwise, you do it manually, which of course can cause you 
trouble as well.  Anyway, getting off topic.  I only intended to report 
some form of success with the wx backend.

Dears, I want to interpolate some irregular data using radial basis.
Can I interpolate only the data that falls inside a circle (or a
polygon)?

TIA

Are you using a framework install of Python? Also, does the MacOSX backend work with plain python instead of ipython?

Just to be clear -- this sounds like a MacPorts problem, not necessarily 
an OS-X problem.

Does MacPorts not allow a native wx? Maybe becasue you're running 64 bit?

Anyway, I guess that's why I don't use macports for python.

That's what I've been running, and I've had no real issues (Haven't 
tried the OS-X back-end) -- but I'm using the python.org python.

OK -- then a fink issue, rather than a Macports one -- same idea, though.

My impression is that neither fink nor macports do well with Mac GUI 
stuff -- unless you're talking X11.

Hi Gang,

I don't know if it is a problem from nabble, but the 'archives' link from the 
main matplotlib pages goes to a decidedly non-matplotlib page.

The link is http://www.nabble.com/matplotlib---users-f2906.html

Or for the pdf backend,

rcParams['pdf.use14corefonts'] = True

and refrain from using any mathtext formatting.

There isn't a way to embed Type 1 fonts, but you can force matplotlib to 
use the core 14 Postscript fonts only by setting the rcParam "ps.useafm" 
to True.
