A good tutorial on how to make mpl play nice with QtDesigner would be a useful thing to have in the documentation. It would be appreciated if you could take a crack at writing that up.

Subject: Re: [Matplotlib-users] Keep list of figures or plots and flip through list using UI
To: Thomas Caswell <tcaswell@…287…>
Funny thing - shortly after I wrote you - I figured it out. I have a
GUI/Dialog I created with designer that has a push button which cycles
between two plots I stored in a list. If you would like to see my
code, I would be more than happy to share. It isn’t fabulous, but it
show the mechanics. I will also take a look at what you just posted
above.
Much appreciated!

(sorry for the code quality, this is a bespoked gui I wrote as part of my
PhD work, you might be the second person to ever read this code) for a Qt
object that wraps up a Figure in a nice-embedded way. Using this directly
you can keep a list of these objects around and show/hide them using
standard Qt methods. Modifying this a bit you could make this class based
on a standard Qt widget, embed them all in a main window/what have you and
then again use standard Qt methods to show/hide individual plots as you
wish.

I looked at glue as you suggested, but the page says it only supports
python 2.7. As for the Qt examples I can find, all I see how to do is
to feed a single plot widget different data sets - but nothing on
dynamically changing the underlying widget and redrawing. Would you
maybe take a look at my code and tell me what it is I am missing? If
so, I’ll send it to you.
Much appreciated.

No problem - thanks for the reply. I tried your suggestion of keeping
a widget for each plot, but I couldn’t get the main window to refresh
correctly - maybe I was doing something wrong. I’ll give it another
try as soon as I get a chance. In the meantime, I’ll check out glue
as well - it looks pretty cool.
I might bug you one more time if I can’t figure it out, but I am not
in a hurry and I probably just overlooked something. 
Thanks and much appreciated!

The core of the embedding in Qt is at QWidget which contains the
canvas.
Anything you want to do with a QWidget you can do with the canvas.
Independently you need to maintain the mpl level plotting objects (the
Figure, Axes, and Artist objects) (well, you don’t need to, you can
get to
them through the canvas object, but to keep your self sane I highly
recommend keeping track of the mpl objects your self, this linkage is
there
so that GUI generated draw commands can trigger a re-rendering of the
figure).
I would just have a widget for each of the plots you want to have and
then
cycle which one is visible in the main window, that is probably a lot
easier
than trying to attach and detach canvases from Figures.
I would also take a look at glue
http://www.glueviz.org/en/stable/installation.html who may have solved
many
of these problems for you.

Hi all,
I often have scripts that make a lot of plots, and I would like to be
able to create the plots and then have a UI tool that shows a list of
their titles, click on the title and have the plot be drawn in a
window. So far, I have been able to use PyQt to create a UI with a
list box and a Widget to display plots. What I can’t seem to figure
out is how to make a bunch of plots and then have the Window update.
So, in psuedo code:
list of plots =
Go through datasets:
plots.append(plot(dataset))
For plot in plots:
add plot title to UI list, position in list is reference back
into list of plots
On UI:
click on plot name/title
widget draws plot
So - basically like docked plots, except there is just a list to the
side instead (much cleaner IMHO)
I haven’t been able to find any examples from googling. Has any one
been able to do this or seen examples?
Any help or suggestions are appreciated!
Thanks!

Tom et al.,
I don’t know about this exact application… However, a couple of months ago, I asked on the Scipy mailing list about updating the Scipy cookbook page for Qt/Matplotlib (http://wiki.scipy.org/Cookbook/Matplotlib/Qt_with_IPython_and_Designer), but I never got a response. The cookbook example is terribly out of date, so I worked out a pretty simple example that essentially reproduces the Qt backend plotting window. See my post (http://mail.scipy.org/pipermail/scipy-dev/2014-December/020258.html) for an initial version of the code. I may have updated it since that time. If you are asking for an example for the MPL docs, I would be happy to write my example up with some picts, if you could tell me where the most appropriate place in the documentation would be for such an addition.
(However, it sounds like Creator will supersede Designer for Qt5 so…)
