Re: [Matplotlib-users] Fwd: Keep list of figures or plots and flip through list using UI
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 The cookbook example is terribly out of date, so I worked out a pretty simple example that essentially reproduces the Qt backend plotting window.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...)

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.

Re: [Matplotlib-users] Fwd: Keep list of figures or plots and flip through list using UI
Probably in the embedding examples. There was an effort to start a mpl specific cook book a while a ago based around a wx/glade example but I have lost track of where that is.

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! : -- Dive into the World of Parallel Programming. The Go Parallel
