Hello, is there a function like set_ydata() for fill? I am able to
animate with the standard p1 = plot() and p1.set_ydata(), but I don't
know how to do this with fill().
 
Thanks!

You can use a combination of axes() to define where you want the image
and imshow() to define the image.  Use frame_on=False with axes(). You
can pass a PIL image directly to imshow(), and that way you won't have
to use imread, (although you'd have to use Image.open()).

Have selected a GUI toolkit yet? If wxPython is an option, check out OGL 
and FloatCanvas. On e or the other of these may be useful. I'd be glad 
to answer any questions you have about FloatCanvas.

Dear all,

an attempt to update from matplotlib-0.71 to matplotlib-0.84 on
a solaris 5.8 (GCC-3.3.2, Python 2.4.2) machine failed. The error message is:

In file included from src/_na_backend_agg.cpp:24:
src/swig_runtime.h: In function `int SWIG_Python_ConvertPtr(PyObject*, 
void**, 
   swig_type_info*, int)':
src/swig_runtime.h:1128: error: `Py_False' undeclared (first use this 
function)
src/swig_runtime.h:1128: error: (Each undeclared identifier is reported only 
   once for each function it appears in.)
src/swig_runtime.h: In function `PyObject* SWIG_Python_NewPointerObj(void*, 
   swig_type_info*, int)':
src/swig_runtime.h:1236: error: `Py_True' undeclared (first use this function)
error: command 'gcc' failed with exit status 1

The aim was just to install the 'agg' and the 'Tkagg' backends, the problems
seems to arise in the agg2.3 section (matplotlib-0.71 had agg2.2).

I browsed through previous list entries, but this problem seems to be 'new'.
Any ideas?

Thanks for the help,
Martin

I think you mean "harder".

Pylab is for interactive use.  See
http://matplotlib.sourceforge.net/interactive.html
for a discussion of the issues.

So if you can create your figures ahead of time and just 
load them, that's fine.  But if you want to create them
on the fly, you should use Matplotlib's OO functionality.
Maybe the function below will be a bit helpful for
getting started.  (Caution: it's a novices effort.)

Alan Isaac

def show_tkagg(figure,title=''):
	"""Create a new matplotlib figure manager instance.
	"""
	from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
	#_focus = windowing.FocusManager()
	window = Tk.Tk()
	window.wm_title(title)
	canvas = FigureCanvasTkAgg(figure, master=window)    
	canvas.draw()
	canvas.get_tk_widget().pack()
	Tk.mainloop()

One further question.
I'm trying to construct a particular category of graphs. 
I need to establish not only edges between nodes, but also edges between
edges and nodes. 

.-----.
(edge between nodes)

        |
.-------|
        |
(edge between a node and an edge)

Do you know how can I represent this graphs through python, in
particular using network? Is it possible? Many thanks.
All the best,
nico

I'm trying to develop a software in python permitting to construct
graphs. I've one question. Actually this is the "starting point"
question. Do you know how to represent in a graphical way the arrows and
the links between arrows? Furthermore, I will be grateful if you can
inform me about the existence of similar softwares.
Many thanks.
Best,
nico

I don't want to manage each win, each toolbar and each canvas.<br>

I want a gtk interface with no canvas and many independents figures

    Samuel&gt; I have a problem : I wrote a little GUI with glade, python

You should not mix pylab with GUI programming.  You must use OO
matplotlib instead <a class="moz-txt-link-freetext" href="http://matplotlib.sf.net/faq.html#OO">http://matplotlib.sf.net/faq.html#OO</a>.  pylab will
try and manage the figure windows for you, which is causing your
problem.

See examples/embedding_in_gtk*.py and examples/mpl_with_glade.py

    Samuel&gt; When my main scipt is run with the ipython console with
    Samuel&gt; 'run my_gui.py' , it works.  But with 'python my_gui.py',
    Samuel&gt; it doesn't work.


This is a quirk resulting from the fact that in "interactive" mode,
which ipython sets, destroying the last window managed by pylab
doesn't result in a main quit

    Samuel&gt; What is trick ?

See above :-)

Hi,

Sorry...newbie question:

Is there a simple way to add logo images to the plots produced
by matplotlib?  I've attached a sample plot created in IDL
which shows the logo positioning I would like to achieve.
I wasn't able to find any examples that had logos (though
there was a logo.py in the examples tarball that was missing
the .dat file).  Would I basically have to read in the
pngs with imread, resize them, do some voodoo with the figure
layout, and finally imshow them?

Thanks,

Gerald

The best way now is just to add it to lines.py and submit a patch.
With a little work, we could make this extensible, especially along
the lines of recent work my Martin Richter.
