Hi,
I am writing a module which should, among other things, output images, and it
should work both in interactive mode and when imported as a script.
In order for the plotting behavior to be clean, I would like to prepare the
figure separate from pyplot. The reason for this, is that the figure is drawn in
a non-interactive loop, and I don't want to show all the steps as they go.
Moreover, for some reason with ipython inline backend the figure is rendered
twice for no obvious reason. So the preferred behavior of my plotting function
(when pyplot output is requested) should be similar to:
fig = matplotlib.figure.Figure()
ax = fig.add_subplot(111)
ax.plot([1,2,3])
matplotlib.pyplot.<ADD_FIGURE>(fig)
The best approximation to this that I was able to find so far is to use the
following dirty hack (although none of the attributes I use are _private!):
f = plt.figure()
fig.canvas = f.canvas
f.canvas.figure = fig
However this is still problematic: if the interactive mode is on, then rendering
of the figure will still be called after these two attribute. Moreover in
IPython notebook without inline plotting it will result in an opened GUI window,
but GUI mainloop not running.
So here's my question: what's the best way to achieve the behavior that I want?
Thank you,
Anton
I don't have a good answer to this and have had to implement such a
thing in an outstanding pull request (in my case, I have a figure
which has been un-pickled and needs re-attaching to pyplot).
My proposed mechanism goes something like:
figure = matplotlib.figure.Figure(...)
import matplotlib.pyplot as plt
mgr = plt._backend_mod.new_figure_manager_given_figure(num, self)
Obviously this doesn't even exist on master yet, so if you need this
functionality from a version before this you will have to reverse
engineer the pyplot.figure function.
HTH,
