Spyder / iPython inline plot figure size

When I have a figure plotted from a script, I am able to vary the figure size as desired:

plt.figure(1,figsize=(20,20),dpi=72)
plt.imshow(a)
plt.show()

but when I do this in the iPython console, I cant get the figure size to vary. Why is this happening?

(Spyder maintainer here) By default the figures created in the Spyder IPython console are PNG files of fixed size.

If you want to zoom in/out or pan to left/right in a Matplotlib figure, you need to change your graphics backend from Inline (the default) to Automatic. You can do this by going to the menu

Tools > Preferences > IPython console > Graphics > Graphics backend

After doing this and restarting the kernel of the IPython console, or creating a new console, all Matplotlib figures will be created in a new window with controls for zooming and panning.

Finally, if you want to switch between Inline and Automatic while working in the console, you need to run these commands

  • %matplotlib inline to select the Inline backend.
  • %matplotlib qt5 or %matplotlib qt (depending if you're using Qt4 or Qt5) to select Automatic.
