However, to maintain that position, matplotlib must continue to evolve. Complementary or alternative libraries are appearing at an increasing rate, including browser-based plotting and GPU acceleration. To maintain its leadership position for the next decade, Matplotlib must interface with these alternatives while simultaneously expanding its capabilities and becoming easier to use and learn. Matplotlib’s large existing user base (greater than 50,000) means that new developments need to be carefully balanced with maintaining existing interfaces. With the large user and code base comes a significant maintenance and user-support burden. These responsibilities currently account for a majority of the core-developer time spent on matplotlib and has resulted in both the code base and community being in a healthier state than ever before. Even 6 years ago there was no automated testing to speak of and the number of contributors continues to soar on github. However, this effort is, for the most part, done on a volunteer basis in the nights and weekends of the core developers. To go beyond this maintenance level—to make step-change improvements for the benefit of matplotlib’s users—will require funding for full-time developers. Inspired and encouraged by the example of IPython, we would like to begin the process of fundraising. Managing funding on the needed scale is a complex and time-consuming process. Thankfully, NumFOCUS, a 501(c)3 charity organisation co-founded by John Hunter, offers a fiscal sponsorship agreement to minimize the administrative and legal burden on open source projects. We would like to enlist NumFOCUS as our agents in all legal and financial matters, including banking, accepting donations as a non-profit, payroll, and access to legal counsel. As part of the agreement, NumFOCUS would charge a percentage of all funds raised to cover their costs. The full text of the agreement is attached. To comply with the legal and accounting requirements of a non-profit, matplotlib needs to form an administrative body to interact with NumFOCUS and direct the disbursement of any funds. The proposed initial members of the body, are myself (Mike Droettboom), Eric Firing, Phil Elson, and Thomas Caswell, with Thomas acting as the point of contact with NumFOCUS. In practice, signing an FSA will have very little impact on the matplotlib project itself - it will still be BSD-licensed and community-driven as it has always been, and the only motivation for doing this is to give us an opportunity to apply for funding to do more work on matplotlib. We'd like to canvas the community's opinion on the matter, but to put a concrete timeline on the discussion, we would like to propose signing an FSA with NumFOCUS in 3 weeks (Feb 10th 2015) unless there is a major community discomfort with us doing so.

Re: [Matplotlib-users] Animate on Mac O$
Hi Ryan, In matplotlib, drawing is done as part of the call to figure.draw(renderer). The MacOSX backend makes this call from the event loop callback (i.e., the drawRect function in src/_macosx.m). Outside of the event loop callback, the graphics context (CGContextRef on Macs) is undefined, and no drawing can take place. In the animations module, event_source is a timer that periodically calls _step, which calls _draw_next_frame, which calls _post_draw to do the blitting. But since the timer lives outside if the event loop, blitting will fail on Macs; there simply is no graphics context to draw to. The solution is to split the blitting into two parts: - A front-end blitting function that tells matplotlib to blit (this is the function called by the timer) - A back-end blitting function that does the actual blitting (as part of the call to figure.draw(renderer); the back-end blitting function is implemented in the backend). In a sense, this is the same as for the other graphics functions (e.g. there is a front-end plot function, and a back-end draw_path function). See the discussion here for more information: https://github.com/matplotlib/matplotlib/issues/531 (this discussion also went into other issues though). Best, -Michiel.

I'm working on some computer vision algorithm and I'd like to show how a numpy array changes in each step. What works now is that if I have a simple imshow( array ) at the end of my code, the window displays and shows the final image. However what I'd like to do is to update and display the imshow window as the image changes in each iteration. So for example I'd like to do: import numpy as np import matplotlib.pyplot as plt import time array = np.zeros( (100, 100), np.uint8 ) for i in xrange( 0, 100 ): for j in xrange( 0, 50 ): array[j, i] = 1 #_show_updated_window_briefly_ plt.imshow( array ) time.sleep(0.1) The problem is that this way, the Matplotlib window doesn't get activated, only once the whole computation is finished. I've tried both native matplotlib and pyplot, but the results are the same. For plotting commands I found an .ion() switch, but here it doesn't seem to work. Q1. What is the best way to continuously display updates to a numpy array (actually a uint8 greyscale image)? Q2. Is it possible to do this with an animation function, like in the dynamic image example? I'd like to call a function inside a loop, thus I don't know how to achieve this with an animation function. View this message in context: How to update matplotlib's imshow() window interactively?

Re: [Matplotlib-users] Pan/Zoom can't work with blitting
Hi Clare, Which backend are you using, and can you show an example script? The blitting functions are a bit unusual as they try to draw stuff to the figure outside of the event loop. This is e.g. causing problems with animations, which makes use of the blitting functions. We have been looking at that recently (see https://github.com/matplotlib/matplotlib/issues/531) but we haven't come up with a solution yet. Solving this issue may also fix your problem (which sounds like an event loop problem), so you may want to follow issue 531.

Now, when I click on the 'Pan/Zoom' button or the 'Zoom to rectangle' button on the Navigation Toolbar, my plot becomes empty.

Re: [Matplotlib-users] Accelerating PDF saved plots
Hi Eric, Jouni, Thanks for your replies. I opened an issue here: https://github.com/matplotlib/matplotlib/issues/992 and wrote an outline of how the PDF backend can be simplified by making use of gc.restore to keep track of the graphics context. In essence the PDF backend would then follow the same logic as the Cairo and Mac OS X backends, so it may be good to compare to these (especially the Cairo backend, since it's written in pure Python and easy to understand).

OK, that is good to know. The Apple-supplied python is not installed as a framework; I don't know for the Enthought distribution.

Re: [Matplotlib-users] Animation example error on Mac after installation
The animation code is currently not fully implemented in the MacOSX backend because the way the general framework of animations is set up in Matplotlib (at least last time I checked) is not compatible with drawing on Mac OS X. In particular, the problem is that on Mac OS X all drawing should be done from inside the event loop; the animations code also tries to draw outside of the event loop. Somebody would have to go through the animations code in matplotlib to sort this out.

While the initial 2D graph examples work great, when testing any of the animations, such as: http://matplotlib.sourceforge.net/examples/animation/simple_anim.html I always get the same error: File /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/animation.py, line 248, in _blit_clear a.figure.canvas.restore_region(bg_cache[a]) AttributeError: 'FigureCanvasMac' object has no attribute 'restore_region' Since restore_region is only in backend_agg.py and not in backend_macosx.py, After reading more on this, I thought this might be corrected by re-installing from source and setting the setup.cfg to macosx = True and backend = MacOSX prior to building, but this did not correct the issue. Also, changing backend: Agg to backend: MacOSX in: /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/mpl-data/matplotlibrc didn't work either.

Re: [Matplotlib-users] matplotlib 1.1 TypeError: a float is required problem
The problem seems to originate from this line in lib/matplotlib/sankey.py:
patch = PathPatch(Path(vertices, codes),
fc=kwargs.pop('fc', kwargs.pop('facecolor',
'#bfd1d4')), # Custom defaults
lw=kwargs.pop('lw', kwargs.pop('linewidth',
'0.5')),
**kwargs)
Note that the linewidth is set to the string '0.5' rather than the float 0.5.
gc.set_linewidth is then called with the string '0.5' as the argument, which
triggers the error. If I replace '0.5' by 0.5, the example runs fine with the
MacOSX backend.
Is there a reason why this needs to be a string here? I would think that in
general gc.set_linewidth should only accept floats and ints.

Re: [Matplotlib-users] animations in macosx/wxagg
Dear Chris,
- can the native macos backend be used for animation?
Yes.
What's the
equivalent of gobject.idle_add or gobject.timeout_add?
If you use the recent backend-independent animation code, you won't need those.
See examples/animation/simple_anim.py on github for an example (this code is
not yet in an official release). However, blitting won't work, so you'll need
to switch that off.
Anything special needed for the blitting approach to work?
Currently it won't work with the MacOSX backend. For blitting to work with the
MacOSX backend, we won't just need changes to the backend code (which is
relatively straightforward) but also to the upstream
lib/matplotlib/animation.py code. We will need to rethink the logic of blitting
with animation, in particular when to store the figure to be blitted, and when
to do the actual blitting. In the current version of
lib/matplotlib/animation.py, the figure to be blitted gets stored after the
figure is modified but before the screen is updated. With the other backends,
this results in the unmodified figure being stored; with the MacOSX backend,
this results in the modified figure being stored, so if you then blit it you
will see an incorrect background.
--Michiel.
- What needs to be done to get WXAgg blitting? I have code
like this:
...
matplotlib.use('WXAgg')
...
def update():
...
# restore, blit etc
wx.WakeUpIdle()
...
wx.EVT_IDLE(wx.GetApp(), update)
...
On Linux this draws the first screen and pauses. If I move
the mouse
around I see the updates. As soon as I stop, so do the
updates. What
am I missing? (BTW I get the same behaviour from
animation_blit_wx.py
from the examples page). This is 1.0.1 on Linux, although
I'm still
using 0.99.1 as well.
thanks for any help,
cheers, chris

Re: [Matplotlib-users] mpl 1.0.1 + snow leopard + python 2.7
I have compiled matplotlib with a 64 bit Python on Mac OS X (using setup.py) for the MacOSX backend. It's not as hard as it may seem. You will need 64-bit (or multiple-architecture) libraries for zlib, libpng, etc. You may have those already; you can check that by running file on the library. For example: $ file /usr/local/lib/libpng.dylib /usr/local/lib/libpng.dylib: Mach-O universal binary with 2 architectures /usr/local/lib/libpng.dylib (for architecture i386):Mach-O dynamically linked shared library i386 /usr/local/lib/libpng.dylib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64 If the library is 32-bit only, then you will have to compile your own zlib, libpng etc. If the library includes 64-bit, then you just need to compile matplotlib. --Michiel. --- On Tue, 2/22/11, Gideon Simpson simp...@math.toronto.edu wrote: From: Gideon Simpson simp...@math.toronto.edu Subject: [Matplotlib-users] mpl 1.0.1 + snow leopard + python 2.7 To: matplotlib-users@lists.sourceforge.net Date: Tuesday, February 22, 2011, 1:35 PM Hi, I have OS X 10.6.6, Python 2.7.1 installed from the binary at python.org, and I am trying to get mpl 1.0.1 running.

Thanks for your reply.
But nowadays drawing is done through draw_idle, so we don't trigger additional
drawing even if interactive is True. In your example, if run as a script, there
is no drawing until a call to show() is made, regardless of whether interactive
is True or False.

Yes, this is the desired behavior. The interactive :
True parameter
is useful when working interactively from the shell, when
want to do
plt.figure()
plt.plot([1,2,3])
plt.xlabel('a label')
and have the figure show up on the figure call and update
on the plot
and xlabel call. This is most definitely not what you
want to do in a
script, because you don't want to pay for the draw until
the end (when
a call to show is made). This is discussed at

In the MacOSX backend, everything is single-threaded, so this won't occur. I am not sufficiently familiar with the non-MacOSX backends to give a detailed answer, but with multiple threads the idle refers to the Python thread being idle rather than the GUI thread being idle. In other words, when there are no more Python commands left to be handled, the GUI thread is notified that it should start redrawing. Are you proposing that we can get rid of the interactive setting entirely, always call draw on pyplot commands, and let the idle handler save us from doing repeated draws? Yes (I assume you mean to always call draw_idle on pyplot commands). If there are then still cases where we do get repeated draws, then that is a bug.

In the gtk backend, draw_idle calls gobject.idle_add
Thus, idle means the gui event loop has no higher
priority events. Is
this condition reached only at the end of the script?
With Python, there is only one thread (running both Python and the GUI). So the
GUI event loop won't start until the end of the script, so there is no
inadvertent redrawing regardless of interactive being True or False.
With ipython, I am not sure if they are using one thread, or one thread for
Python and one thread for the GUI. But in practice, in ipython I also don't
find any evidence of inadvertent redrawing. For example, this script:
import matplotlib
matplotlib.use(gtkagg)
import matplotlib.pyplot as plt
import numpy
x = numpy.random.random(40)
y = x + numpy.random.random(40)
plt.figure()
plt.hexbin(x, y, gridsize=300)
for i in range(1000):
plt.xlabel('a label')
plt.show()
both with python and ipython take an equal amount of time regardless of
interactive being True or False. If there were any redrawing after each call to
plt.xlabel, this script would take forever.
Reminder: the interactive setting controls
draw_if_interactive, which is
what we are talking about here, but also whether or not
show() blocks.
So we may not need draw_if_interactive, but unless we can
dispense with
show entirely, we will still need an interactive setting.
If matplotlib were always interactive, then I don't see a good reason for
non-blocking show().
Returning to the issue raised by the OP, however, the
question is
whether the present MacOSX behavior (windows pop up) or the
non-MacOSX
behavior (they don't in non-interactive mode until/unless
show() is
called) is what we really want. It seems to me that
we should preserve
some way of getting this second behavior.
I agree. For example, if a user wants to make a figure for the sole purpose of
creating a PNG file, there should be a way to do this without the figure
popping up as a window.

Michiel,
With some digging around in my own code I have been
able to reproduce the bug with the matplotlib example. My
code uses wxPython and somewhere it sets the backend to 'WX'
(this seems to require a bit more than simply 'import wx'
but I haven't pursued what it might be ... there are several
thousand lines of code before I get to the plotting).
the code below triggers the problem
import wx
import matplotlib
print 'matplotlib backend',matplotlib.rcParams['backend']
matplotlib.use('WX')
print 'matplotlib backend',matplotlib.rcParams['backend']
from pylab import *
x = arange(100.0); x.shape = 10,10
interp = 'bilinear';
lim = -2,11,-2,6
subplot(211, axisbg='g')
title('blue should be up')
imshow(x, origin='upper', interpolation=interp)
subplot(212, axisbg='y')
title('blue should be down')
imshow(x, origin='lower', interpolation=interp)
show()
if I set the backend to WxAgg then the problem doesn't
occur and if I don't set it all (so its MacOSX) then all is
fine. In the example above the top graph is fine but the
lower one is solid yellow. This behaviour is different from
my code which shows the same image for both origin='upper'
and 'lower'. My platform is enthought 6.1-1 with matplotlib
0.99.1.1.
Given that WXAgg works are there any are the implications
of WXAgg early in my plotting part of the code (this may
result in multiple calls to set the backend) versus letting
matplotlib itself set WX. I just tried to set WXAgg
immediately after the first 'import wx' after program
startup but it had set to WX by the time it got the place
where the plots were made.
I haven't been able to replicate this bug. With all
matplotlib versions
I tried (including 0.99.0, 0.99.1., 0.99.1.1,
0.99.1.2, 1.0.0, and the current source code in svn), this
example works correctly with the Mac OS X backend.
Garry, what is the exact code that you are using?

I saw in one of the post of Michiel de Hoon dating back 2008 that the MacOsX backend does not allow for integration of matplotlib within a cocoa application, I was wondering if it is still the case. Maybe does not allow is too strong an expression. The MacOSX backend was not designed to be integrated within a cocoa application, but somebody sufficiently familiar with cocoa may be able to find a way to do so. Also, I tried to find some tutorial or example showing how to use the two backend but could not find one, maybe i overlooked something and would be grateful if someone could point it to me.

What are the requirements for guiEvent? If I call

that in.
It looks like you may be having a problem because the
leave_notify_event is getting called more than once, or is
called for
a figure that has not been entered. Check the logic
in
backend_bases.FigureCanvasBase.leave_notify_event

It looks like your figure_leave_event is being triggered
with
LocationEvent.lastevent = None (so it is not a problem with
your
guiEvent). This could happen if a leave event was
processed *before*
and enter event (which sets the lastevent), or if a leave
event was
processed twice.
Hopefully this will help you drill down into the source of
the problem

Re: [Matplotlib-users] Large figure sizes get squashed or clipped?
I think the best solution to this problem is to have scroll bars in the figure
window if needed. Depending on the size of the figure (in physical units), the
size of the window containing the figure, and the zoom factor the scroll bars
would appear or disappear. This would require some modifications to all GUI
backends.
The same problem occurs in the Mac OS X backend, where the figure window size
can be smaller than the requested size if the requested size is larger than the
monitor size. See bug 2891502:
http://sourceforge.net/tracker/?func=detailatid=560720aid=2891502group_id=80706

Is there some limitation on figure sizes?

Re: [Matplotlib-users] cannot plot in loops with matplotlib 0.99. 0.98 works fine
Any idea why there is such a difference between 0.98.5.3 and 0.99 ?? Drawing the whole figure once, when no further Python input is available, is much more efficient than drawing after each plot() command. For some figures, matplotlib 0.98.5.3 becomes extremely slow. Thanks JJ, but unfortunately this is not the solution. draw() gives the same result. - and I am running this as a script (running it from ipython shell). The problem in your script is that the event loop never kicks in. Unfortunately, Python has no support for event loops in general, which makes this hard to solve. One option is to use raw_input() between calls to plot(), but then each time you have to hit enter to get the script to proceed. --Michiel. --- On Mon, 9/7/09, tva t...@brygge.dk wrote: From: tva t...@brygge.dk Subject: Re: [Matplotlib-users] cannot plot in loops with matplotlib 0.99. 0.98 works fine To: matplotlib-users@lists.sourceforge.net Date: Monday, September 7, 2009, 3:17 AM Thanks JJ, but unfortunately this is not the solution. draw() gives the same result. - and I am running this as a script (running it from ipython shell).

Re: [Matplotlib-users] show() problem in Mac OS X 10.5.8
Does anybody know why the show._needmain stuff is needed in the show() function
in backend_tkagg.py? Currently, this function is as follows:
def show():
Show all the figures and enter the gtk mainloop
This should be the last line of your script. This function sets
interactive mode to True, as detailed on
http://matplotlib.sf.net/interactive.html
for manager in Gcf.get_all_fig_managers():
manager.show()
import matplotlib
matplotlib.interactive(True)
if rcParams['tk.pythoninspect']:
os.environ['PYTHONINSPECT'] = '1'
if show._needmain:
Tk.mainloop()
show._needmain = False
show._needmain = True
If I remove the show._needmain stuff, as in:
def show():
Show all the figures and enter the gtk mainloop
This should be the last line of your script. This function sets
interactive mode to True, as detailed on
http://matplotlib.sf.net/interactive.html
for manager in Gcf.get_all_fig_managers():
manager.show()
import matplotlib
matplotlib.interactive(True)
if rcParams['tk.pythoninspect']:
os.environ['PYTHONINSPECT'] = '1'
Tk.mainloop()
then the function still seems to work fine, and multiple show()s also works.

The one 'preliminary' solution I found is
using

Here is and example,

raw_input('Type Enter')
clf()
plot([1,2,3,4,5])
raw_input('Type_Enter')
clf()
plot([1,2,3,4,5])
show()
With this approach, I can press the enter when I want
to

Thanks Ryan,
Hm.. it's a bit strange.. I just installed matplotlib
at Ubuntu using the package manager :)
And, another linux machines (red hat enterprise) can do
this too. For the RHELs, I compiled matplotlib source code
by myself.
figure() works very well, but what I want to do is to check
the plots one by one and thus
I can exit the script at any time I want (because I usually
have lots of figures to check and I don't want
to pop up every of them at the same time..)
Anyway, thank you very much!

Re: [Matplotlib-users] Thanks!
Originally, the Mac OS X backend was much faster than the other backends because of how the event loop was organized. Currently, most (I'm not sure about the wx backends) backends use the event loop in the same way as the Mac OS X backend, and are about equally fast (provided that you are using one of the Agg-based backends). There may be some minor difference in drawing quality. There may also be some difference in robustness compared to a more generic backend (not due to the backend itself, but the underlying GUI code). Last but not least, the Mac OS X backend does not need an external GUI library (like wx or pygtk); only Python itself and NumPy are needed. --Michiel --- On Sat, 8/1/09, Kaushik Ghose kaushik_gh...@hms.harvard.edu wrote: From: Kaushik Ghose kaushik_gh...@hms.harvard.edu Subject: [Matplotlib-users] Thanks!

Re: [Matplotlib-users] current svn fails to build on mac
The /usr/X11R6/lib is included because it is listed in setupext.py under basedir['darwin']. Could you try and remove /usr/X11R6/lib from basedir['darwin'] in setupext.py to see if everything still compiles and links (both the Mac OS X backend and other backends)? At least, I don't see any libraries that needs to be linked from /usr/X11R6/lib. Compilation and linking without /usr/X11R6/lib works for me, but it'd be nice if you could double-check this on your system before I submit a patch to the matplotlib developers. --Michiel. --- On Fri, 7/10/09, Robin robi...@gmail.com wrote: From: Robin robi...@gmail.com Subject: Re: [Matplotlib-users] current svn fails to build on mac To: Michiel de Hoon mjldeh...@yahoo.com Cc: matplotlib-users@lists.sourceforge.net Date: Friday, July 10, 2009, 6:59 AM On Fri, Jul 10, 2009 at 11:45 AM, Michiel de Hoonmjldeh...@yahoo.com wrote: It's probably the -L/usr/X11R6/lib that is causing a problem.

The error you're seeing is described in this technical note from Apple: http://developer.apple.com/qa/qa2007/qa1567.html One thing that changed between 0.98.5.3 and the current SVN version is that we're now using matplotlib's path cleanup code, which is in C++.

I copied setup.cfg.example to setup.cfg and have macosx = False but it doesn't seem to have any effect. python setup.py config still reports Mac OS X native: yes. Thanks Robin PS - some minor comments about the sourceforge download page (I dont know if these can be changed): On the summary page ( http://sourceforge.net/projects/matplotlib/ ) the download now link which I would think should point to the latest release point to 0.91. Then when you do 'view all files' matplotlib-maintenance is the default expanded branch of the tree with latest version 0.91.4. To get the real new version you have to close this tree or scroll down to the normal matplotlib branch. If I didn't know the versions to look for beforehand I think this would be really confusing - can you make matplotlib the default instead of matplotlib-maintenance? Also I went to the Developer page to find the svn repo http://sourceforge.net/projects/matplotlib/develop and followed the instructions there which of course started to pull in the whole repo. When I found it taking a long time I noticed that I was getting branches etc I didnt need. I know this is covered with the correct command in the install page, but I thought it would be handy to change it here as well to avoid someone else making the mistake I made. These are very minor things and normally I wouldn't bother mentioning, but since the matplotlib website etc. seems so nice I figured there is someone who cares about this stuff - although I'm not sure whether its possible to change this stuff in sourceforge. -- Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!

Indeed the formulas look like bitmaps. Previously the Mac OS X backend indeed used its own machinery to create PDF files. Recent versions of the backend in SVN, however, use matplotlib's pdf backend. So the problem should go away if you use matplotlib from SVN. The Mac OS X backend itself can actually be fixed to use vector graphics on screen instead of bitmaps. That will need some time, but I'll get round to it one of these weeks. --Michiel. -- ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
Re: [Matplotlib-users] New contourf() drawing polygon boundaries for some reason?
I can't reproduce this error with the current code in SVN trunk, but I remember
seeing this bug a while ago. So I'm guessing that this bug has already been
fixed in SVN. Zane, could you try installing the latest matplotlib from trunk
and see if you still see this bug?

Thanks for the thorough investigation.
Michiel: can you look into why the macosx backend is
drawing the
strokes around the polygons? Probably as simple as
inadvertently
ignoring an argument.
I'll look into the path simplification-related issues.

Looking at the PDF and PNG output using the macosx

fine. It's only the GUI output which is for some
reason outlining the

x = uniform(-2,2,npts)
y = uniform(-2,2,npts)
z = x*np.exp(-x**2-y**2)
# define grid.
xi = np.linspace(-2.1,2.1,100)
yi = np.linspace(-2.1,2.1,100)
# grid the data.
zi = griddata(x,y,z,xi,yi)
# contour the gridded data, plotting dots at the

In both of these cases (path.simplify: True|False), the PNG

Also, since the Agg backend doesn't have an associated

Re: [Matplotlib-users] Wxpython, Matplotlib and draw_artist
I am not sure if this is related, but maybe it can give you a hint. I looked at the copy_from_bbox/restore/draw_artist code a long time ago, and if I remember correctly by calling restore_region function, you're drawing directly onto the canvas. In contrast, if you do e.g. plot(x,y), you're not drawing directly; you're just telling matplotlib what you want to plot, but the actual plotting is done by matplotlib by calling figure.draw(renderer). Typically, this happens from inside the event loop, which is how things are supposed to be. On the other hand, restore_region bypasses the event loop, which is usually not a good idea. --Michiel --- On Wed, 5/6/09, Elan Pavlov epav...@gmail.com wrote: From: Elan Pavlov epav...@gmail.com Subject: [Matplotlib-users] Wxpython, Matplotlib and draw_artist To: matplotlib-users@lists.sourceforge.net Date: Wednesday, May 6, 2009, 2:05 PM Hi, I can't get wxpython to play well with matplotlib and draw_artist.

Re: [Matplotlib-users] Wxpython, Matplotlib and draw_artist
Looks like we have the culprit. Is this a bug or an undocumented feature I think that the current code is a bit of a hack that sometimes works and sometimes doesn't, depending on which backend you use. and is there anything I should do about it (i.e., report it)? Yes, I think so. It's not super difficult to find a solution, but it will need some discussion with the matplotlib developers to find the best way to fit this in with the existing matplotlib code. More importantly, do you have any idea how to fix the problem In principle, it's simple. You'll need to split up the restore_background function in a frontend_restore_background and a backend_restore_background (arbitrary names, of course). The frontend_restore_background is what the user uses to tell matplotlib which background should be restored where. Inside the event loop, the backend_restore_background uses this information to do the actual blitting. or how the event interactions with wxpython work? I don't think it matters much, as long as the actual drawing is done from inside figure.draw(renderer). Is it even feasible to do a restore_canvas within the event loop Absolutely. There is no essential difference between drawing a line or blitting a background. Imagine the code in figure.draw(renderer) to be something along the lines of blit a background, if any draw the lines, if any fill shapes with color, if any draw the text, if any ... or will this slow it down to the extent of being useless? I wouldn't know why. --Michiel. --- On Thu, 5/7/09, Elan Pavlov epav...@gmail.com wrote: From: Elan Pavlov epav...@gmail.com Subject: Re: [Matplotlib-users] Wxpython, Matplotlib and draw_artist To: mjldeh...@yahoo.com Cc: matplotlib-users@lists.sourceforge.net Date: Thursday, May 7, 2009, 10:23 AM Hi, By George, I think you've got it!

[Matplotlib-users] Matplotlib interactive with gtk, gtkcairo, gtkagg backends
Hi everybody, For those of you that are using the gtk, gtkcairo, or gtkagg backends: Today pygtk version 2.15.0 became available, which is the first pygtk that can be used interactively from both python and ipython. If you're using ipython, be sure to wait for release 0.10.0 of ipython before upgrading to pygtk 2.15.0; older versions of ipython may not work correctly. If you're using regular python, you can install pygtk 2.15.0, set interactive to True in matplotlibrc, and you should be all set. Unfortunately, this won't work with IDLE; this is because of the lack of event loop support in Python itself.
