Re: [Matplotlib-users] assigning a plot object to a figure Emmanuel Mayssat Mon Apr 02 16:00:45 2012

Well, not sure if that is supported, but I found a way !:
        [...]

        self.fig1 = Figure(figsize=(width, height), dpi=dpi)
        self.fig2 = Figure(figsize=(width, height), dpi=dpi)
        self.axes1 = self.fig1.add_subplot(223)
        self.axes2 = self.fig2.add_subplot(221)

        [...]
        self.axes2.plot([0,1])
(1)     self.axes2.set_figure(self.fig1)
(2)     self.fig1.add_axes(self.axes2)

Note that (1) and (2) are required in that order!
From the code above, if I show the fig1, then I see axes1 and axes2 on the 
figure....


Summary:
I created the axes2 independently of fig1

PS: I want to use my axes2 as an object to sent to my Qt widget (a blank 
figure/canvas)

As far as I can see, you can't.  The figure is deeply embedded in the 
Axes object; that's why the figure is an argument in Axes.__init__().

I don't think you can.  It looks to me like Axes.set_figure should be 
clearly marked as a private method, not to be used except in 
Axes.__init__().

Short of a major refactoring of mpl, I think you will need to find some 
other way of accomplishing your ultimate aim.
