The code does not seem to be runnable and does not give a sensible result. I used this code
fig, axs = plt.subplots(2, 2, constrained_layout=True)
for ax in axs.flatten()[:-1]:
ax.plot(np.arange(10))
axs[1, 1].plot(np.arange(10), label='This is a plot')
leg = axs[1, 1].legend(loc='center left', bbox_to_anchor=(0.8, 0.5))
leg.set_in_layout(False)
wanttoprint = True
if wanttoprint:
leg.set_in_layout(True)
fig.do_constrained_layout(False)
fig.savefig('outname.png', bbox_inches='tight')
plt.show()
i.e. the code from the matplotlib 3.0 documentation with wanttoprint = True but it gives an error AttributeError: 'Figure' object has no attribute 'do_constrained_layout'.
Assuming that what is meant here is set_constrained_layout, the problem is that the figure shown deviates from the one obtained via wanttoprint = False. So it seems it's not possible to show the figure after saving it?
Using the second code (the one with fig.legend()) everything works as expected.
In my eyes there are the following things to do:
- Correct the first code to be runnable and produce the expected outcome for both settings of
wanttoprinton screen and as saved image. - Explain the reasoning behind turning the legend in layout option first off then on etc.
- Add a savefig line to the second example to make is clear that this is to be understood parallel to the previous example.
