Changing matplotlib window title is throwing strange error

Question

I’m using python 3.6 in Jupyter lab on a linux mint machine to run this snippet of code

import matplotlib.pyplot as plt

fig = plt.figure()
man = plt.get_current_fig_manager()
man.window.setWindowTitle("New Title")

..it returns the following error message:

AttributeError: 'FigureManagerBase' object has no attribute 'window'

I have checked the GUI backends. All are available and all of them return this error even if I force the backend using …

import matplotlib
matplotlib.use(<gui>,warn=False, force=True)

…before importing pyplot. The code has been working OK in Spyder but I’ve had to move to Jupyter. The matplotlib docs say that FigureManagerBase attributes include ‘window’. I’m stumped
