I was wondering if there was any instruction anywhere how to get the handles to fig,ax from the PPSD.plot() method… I just wanted to tweak the size of the figure, and add a few curves with the seismometer noise levels, but can’t figure out how to hack myself around it.
Tweaking figure size might not be possible like this via the API though,
as the figure is always opened inside the plot routine (and I don't
think you can easily resize an already created Figure). We could add an
Option ``plot(..., fig=None)`` to enable this if needed but that won't
help you right now. Short term solution to tweak figure size is probably
to monkey-patch the source code of your live obspy installation.
