pls use is_list_like, and check the input length are correct. Note that all the axes may not require title when you specify layout

Ok I'll use is_list_like. I purposely did not check the lengths as a feature. As it's written, if you only provide a list of two strings, but the plot has 3 suplots, the first two subplots will have a title and the third will be left without one.

for (ax, title) in zip(self.axes, self.title):
ax.set_title(title)
else:
self.fig.suptitle(self.title)
else:
self.axes[0].set_title(self.title)

Can you leave the starting sentence "Title to use for the plot" ?
