FWIW, I think my "Anatomy of Matplotlib" tutorial I gave at SciPy 2013
struck a balance between pyplot and the OO interface. I welcome any and all
feedback on that tutorial which I plan to give again next year as well as
an intermediate "Anatomy of Matplotlib" tutorial.

nice! -- ( though I sure wish Qhull did constrained delaunay...)

Why bother, why not just always build the internal version?

(for that matter, same with agg)

Wouldn't it be a lot easier and more robust to be sure that everyone
is running the exact same code?

What are the odds that folks are using qhull for something else, and
even more to the point, what are the odds that the duplication of this
lib would matter one wit?

This isn't like LAPACK, where folks have a compellling reason to run a
particular version.

-- just my thoughts on how to keep things simpler.

+inf

Even better, dump pyplot and use primarily the OO API. Asside from
folks that dont want to change anything when moving from Matlab, we
should all be using teh primarily OO API.

is it really that hard to type:

ax.plot()

rather than

plot() ?

And when you move away from interactive use (and we all should fi your
typing more than 4-5 lines of code) teh OO interface is a much better
way to go.

(I know, iPython notebooks allow you do do a LOT with esentially an
interactive interpreter, but still.....)

Anyway, I've always thought it was a real shame that most of the
tutorials on MPL out there get people started on what I'm convinced is
the wrong foot.

I've never seen that failure before...

I wonder if Pierre Haessig has any thoughts, as the author of that test...

Hi,

I'm testing the binary installer build:

https://travis-ci.org/matthew-brett/mpl-osx-binaries/builds/12703220

and I'm getting a test failure on Python 3.3 (not Python 2.7):

Thanks for the feedback.  I was thinking that a refactor to pull out the 
communication layer would be really nice.

I didn't change the WebAgg backend because I figured you wanted it 
around still.  I figured a plain old diff with the file would reveal 
changes.

Anyways, thanks for the pointer to the refactor commit.  I hope to look 
at this again sometime soon.

Sorry to take so long to get to this. This is a nice piece of work.

The most obvious thing is that this is a copy-and-paste of the existing 
WebAgg backend -- and maintaining the two is going to be much harder 
than building both out of the same pieces.  As of 6389d14f, the WebAgg 
backend was refactored so that the transport that it uses to communicate 
to the browser is no longer hard coded.  This was done in large part to 
support working with IPyhton in this way.  (That is, it used to only 
communicate with the browser through Tornado, but now it can be anything 
that can send bits back and forth).  There's an example of this in 
`examples/user_interfaces/embedding_webagg.py` that shows how to do this 
(using Tornado, but again, it doesn't have to be). There's no guarantees 
that this interface is sufficient, so it may require some back and forth 
on this to make it all work.

I think the first thing I would do would be to refactor this to use 
that.  It's a little hard to tell what you've changed from the original 
WebAgg backend to get it to support IPython.  If it were built on top 
of, rather than in addition to, WebAgg, that would be more obvious.

Looking through the code I realize that in interactive mode (ipython)
there is no call to show() by default.
And if you call it, it does not call mailoop because is_interactive==Tr
ue
So why is there the restriction to call only once Gtk.main in mailoop?
if it is not called anyway

Why not make that restriction to call Gtk.main in  mainloop dependant
on is_interactive? as the call Gtk.main_quit is in the destroy method

Y yo que culpa tengo de que ellas se crean todo lo que yo les digo?

-- Antonio Alducin --

Sorry, the replay-all is not my default.

In that case it is easier for me to monkey patch just the mainloop to
invoke Gtk.main everytime.

But again, even if we are talking about interactive (ipython), why is
it unbalanced?
I mean calls Gtk.main vs Gtk.main_quit?

Please keep all emails in-band

I was commenting that the issue you are having with getting easy-to-use
pre-built figures in a non-interactive program without dragging pyplot in
is the same as what I think the root of 2503 is and the re-factor I
proposed to make your life easier would also help that case (I think).

The gui backends were (as I understand it, someone please correct me if I
am wrong) built to play nice with ipython to put together a MATLAB-like
interface.  The fact that you can then embed the gui-framework dependent
bits of matplotlib in other gui applications is a nice side-effect, but not
one of the initial design goals.  This is why the `figure_manager` code is
(too-)tightly coupled to _pylab_helpers.

See the examples at http://matplotlib.org/examples/user_interfaces/  making
a window with a canvas + tool bar is pretty easy.

A quick and dirty solution might be to just monkey patch the
figure_manager.destroy function when your app starts up to remove the check
that shuts down the main loop.

@Eric
But this imposses alot of restrictions?
I want to have the GUI backend with the toolbar and everything.
If I do it like you propose, I have to create the figures on the side
when calling from a ipython session. and when calling from my gtk app,
I have to create by hand everything even the toolbars etc...

@Tom, I agree that the problem is within the figure manager.
That is why I asked about the "unbalanced" ways to call Gtk.main and
Gtk.main_quit

I was checking https://github.com/matplotlib/matplotlib/pull/2503 but
I think the solution proposed there does not help me.

As you know I am trying to get the multi-figure-manager accepted or at
least reviewed,
At the end, if the only way to use a nice GUI backend is without
calling it from other GUI, it does not help to have a nice GUI
backend, you will have to redoit anyway.

One of the main limitations that I see is that the top level code in
mplot3d still needed to conform with the basic assumptions of matplotlib's
rendering engine. That being a 2-D + z-ordering renderer. So, top-level
functions like get_path() has to return a 2-D projected form of the
internal 3-D data, and then a zorder value is provided to represent the 3rd
dimension for all the data for that artist object. It is entirely possible
to get at the internal data unmolested, but there is no unified mechanism
for doing so. Sometimes the z-data is stored separately. Sometimes the data
is stored as a Nx3 numpy array. What might be a useful endeavour is to
first look to unify the 3d get/set methods of the art3d classes.

I think the choices are to rewrite do_my_plots to be consistent with 
your embedding, or to run it in a separate process.  For the former 
option, the key is to keep pyplot out of everything except a top layer 
which is used when calling via script or in a pyplot environment (e.g. 
ipython), but which is not used in your gtk3 app.  As an example (sorry 
it is rather long and complex) see 
http://currents.soest.hawaii.edu/hg/pycurrents/file/43a9236c62ff/plot/txyselect.py. 
  Note that pyplot is not even imported except inside a function that is 
used to demonstrate the functionality in script mode.  Therefore all the 
functionality is accessible when embedding by importing the module, so 
long as one does not call that one highest-level function.  To embed, 
one simply includes the contents of that function but without the pyplot 
parts.

Ok,
for me embedding is more of using the canvas directly and putting
inside my own window.
But OK, i give you that.

In that case,
if I have standalone funcion (or class) that can be run alone something like
do_my_plots().... that if run with python myplots.py will display the plots.

How can I add the do_my_plots call to my Gk3 app? and not having to
worry that closing the plot windows will close my gtk3 app?

embedding vs launching is a distinction without a difference, you are
integrating matplotlib with your own gui application.

That said, it would be nice to re-factor the figure_manager classes so they
they make no reference to `Gcf` or anything associated with pylab and could
be easily re-used.

I think that would also help with the issues in
https://github.com/matplotlib/matplotlib/pull/2503

No, your example shows that you *are* embedding.  You are running your 
own Gtk.main().  That's embedding.

Again

In the example the plotting is inside the callback (just for
simplicity), but in reality, the plotting is in another class,
somewhere else that can be called standalone to produce the plots.

If you are embedding matplotlib, do not import `pyplot`.  `pyplot` sets up
a bunch of gui-magic (tm) in the background (as you found in
`figure_manager`).

Hello everybody

Working on one GTK3 app, that calls matplotlib to plot some figures, I
found that closing all the figures from matplotlib kills my app also.
The problem....

Gtk.main() is called only if there is no previous invocation, in my
case, my Gtk3 app invokes main, so the mainloop won't call it again.

#in backend_gtk3.py
#
class Show(ShowBase):
    def mainloop(self):
        if Gtk.main_level() == 0:
            Gtk.main()

But in the "destroy" method of the figure manager calls Gtk.main_quit
everytime that there are no more figures

#in backend_gtk3.py inside destroy method of FigureManagerGTK3
#
if Gcf.get_num_fig_managers()==0 and \
               not matplotlib.is_interactive() and \
               Gtk.main_level() >= 1:
            Gtk.main_quit()


So basically we are not calling Gtk.main but we are Gtk.calling main_quit.
Isn't it more natural to call Gtk.main the same amount of times that
we are going to call Gtk.main_quit?

Adding matplotlib.rcParams['interactive'] = True doesn't help

Here is my little testing code

##############################
#file myapp.py

import matplotlib
matplotlib.rcParams['interactive'] = True
matplotlib.use('GTK3AGG')
import matplotlib.pyplot as plt

from gi.repository import Gtk

class MyWindow(Gtk.Window):

    def __init__(self):
        Gtk.Window.__init__(self, title="Hello World")

        self.button = Gtk.Button(label="Click Here")
        self.button.connect("clicked", self.on_button_clicked)
        self.add(self.button)

    def on_button_clicked(self, widget):
        fig = plt.figure()
        ax = fig.add_subplot(111)
        ax.plot([1,2,3])
        plt.show()

win = MyWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()
#########################

I know this is related to interactive mode, but running from console
>>> python myapp.py
reproduces the problem

Why hasattr(sys, 'ps1') is False? if I am running it from console? how
do I change this?


Thanks
Federico

P.S. Does anybody had the time to check my PR for multi-figure-manager?

I've been working on a backend based on the webagg backend, but that 
uses the IPython Comm architecture at 
https://github.com/ipython/ipython/pull/4195 to send messages instead of 
starting a server and opening websocket connections.  I have an initial 
version in my github ipython-comm branch (see 
https://github.com/jasongrout/matplotlib/compare/ipython-comm).  I'm 
getting confused about how the backend infrastructure works, though, 
like what the purpose for the FigureManager class is, etc.  I'm running 
out of time to work on this now, and I'm hoping that someone will take 
what work I've done here and get it working properly with the matplotlib 
architecture.  If not, I'll probably tinker with this more later.

Thanks,

Jason

I am using Fedora 19, 64 bit, and the distribution's python 3.3.2, and
the most recent version of mpl from git

there seems to be a bug in the starup routine where proper conversion
from bytes to string (as needed for Python 3) is not done

the problem is in

/matplotlib/__init__.py, line 459 ... 460

    459     gs_exec, gs_v = checkdep_ghostscript()
    460     if compare_versions(gs_v, gs_sugg): pass

ipdb> gs_exec,  gs_v
('gs', b'9.07')

where clearly gs_v needs to be str

Could you please make checkdep_ghostscript() to be python3-save by
changing line 334 from

v = stdout[:-1]

to

v = stdout[:-1].decode('ascii')

(my apologies not following the bug report procedures; I hope you can
consider it anyway)

The branch is matplotlib/toddrjen spectral:

Specifically the tests that are causing the problem are in test_mlab.py.  I
tried reorganizing the tests into subclasses and implementing a cleanup
class (that is the current HEAD), but the problem exists even without that
commit.  You can cherry-pick 50c90102a929af5d534e551fd624abffeb9470b8 and
7c1b4db8b2d04826e267781c0de1bcc622f0fdb5.

I have tagged and uploaded 1.3.1.  It is exactly the same as 1.3.1rc2, 
with only the version number being different.  Once the Windows binaries 
are ready, I'll make a broader announcement in the usual places.
