Re: [Matplotlib-users] matplotlib and pyside..

[Gerald Storer]

The version of PySide doesn't really matter so long as it is reasonably 
new.  You need a newer version of Matplotlib and yes, the Github master 
is newer than the current release.

Hi Gerald again,

I recuperated the Pyside last version the 1.0.4 from Pyside's site but 
I obtained the same error message trying to use my former code (same 
used with PyQt with Figure Canvas)

raise ImportError, "Warning: formlayout requires PyQt4>v4.3"
Is the github version even more recent than this one??
Thanks

Lionel

Have a closer look at the example I gave.

The currently released version of matplotlib doesn't support
PySide at all.  So I cheated and simply drew to the generic Agg
backend and then copied the whole figure (gcf = get current
figure) into a PySide QImage object at the end.  The QImage can
then be displayed however you want inside your Qt application.  I
used a QGraphicsScene but there are other options.

If you really wanted to I guess you could use FigureCanvasAgg as
an intermediary - but the process is fundamentally different.  You
can't just drop that it into your PySide app as a widget like you
can with FigureCanvasQTAgg.

As mentioned earlier, if you'd like to use the same code simply
wait for the next release of matplotlib which will support PySide
or you can get a copy of the source from github master today that
also support PySide.

Hi Gerald,

I found yesterday interesting informations on a forum where you
answered about Matplotlib and pyside .. but some details are
missing to make what I want.
Few days ago I developped stuff in PyQt I 'd like to recuperate
in Pyside.. the central difficulty is to import Matplotlib in
Pyside.
In PyQt I was using FigureCanvasQTAgg but in Pyside I couldn't
find something equivalent allowing to link Mpl and pyside..
It seems you're able to make drawings (with add.patch) but how to
do for inserting a figure?

Thanks

Hi Ben,
I did try to roughly replace PyQt4 import by PySide import
in my installed matplotlib but pyplot.plot function led to a seg fault...
(PyQt and PySide where indeed compiled with the same Qt lib)

I'm not skilled enough to go further on...

Thanks for your help,

David

David,

I am not familiar with PySide, so I looked it up.  Please correct me if I am
wrong, but it appears to be an alternative to PyQt for licensing reasons,
and the FAQ says that it is API compatible.  On the python side of
matplotlib, I wonder if using PySide would be as simple as just replacing
all of the "import PyQt" or "import PyQt4" with "import PySide" (and all the
"from PyQt import ...").

Does PySide still use the same compiled Qt libraries that PyQt uses?  If so,
then I don't *think* you need to recompile the Qt backends, but I am not
entirely sure.

Good luck!

[Matplotlib-users] Matplotlib and PySide ?

[David Trémouilles]

Hello,

  Does anybody know if matplotlib work with pyside ?
If it does how to use matplotib with pyside ?

Thanks,

David
