Problem

Problem summary

I cannot change the default location of a figure.suptitle() through the rcParams as I can with the title location of the axis title.

Origin/background

I am tweaking the default settings of Matplotlib to create plots that in appearance match the corporate styling. Most changes have been made by re-setting the default values of certain rcParams.

One of the requirements is the left-alignment of titles of graphs. For the axis title I can set rcParams['axes.titlelocation'] to 'left', as itdefaults to center. I would like to do something similar to the figure's suptitle.

Currently, setting the figure's suptitle only takes defaults rcParams['figure.titlesize'] and rcParams['figure.titleweight']. The other parameters for location and alignment of the suptitle are defaulted in the method's argument definition. My desire is to add these to rcParams as well, and refer hereto as default.

Proposed solution

E.g. expand the rcParams with:

{
    'figure.titleloc_x': 0.5,
    'figure.titleloc_y': 0.98,
    'figure.titleha': 'center',
    'figure.titleva': 'center'
}

And then use these defaults in figure.suptitle(), very similar to how rcParams['figure.titlesize'] and rcParams['figure.titleweight'] are already used as default values.
