specifying exact position and size of axisartist axes


I would greatly appreciate if you could give me some advice.

I would like to make a Cartesian axes with a polar grid shown, just as here in this example:


I have studied this example, I don’t even need ParasiteAxes, just to make those polar grid lines visible.

However, I would like to control the placement and size of such an axis and axisartist.SubplotHost or Subplot don’t

seem to give me enough control. I want subplots of unequal sizes, like in the GridSpec examples.

Normally, one can easily add axes with fixed position and sizes with the convenience method

fig.add_axes() by specifying a “rect” list. How could I control the placement of such axisartist axes


Thank you in advance.
