I'm not sure exactly what you are asking. Axes and Subplot don't have

a _figurePatch, but they do have an _axesPatch, which as you note you

can turn off by using frameon=False. If you want to set it's alpha,

do

ax = subplot(111)

frame = ax.get_frame()

frame.set_alpha(0.0)

Is this what you are looking for?
