Keep list of figures or plots and flip through list using UI

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.

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. :slight_smile:

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…)
