I would like to plot a smaller chart over a large chart in matplotlib in order to maximize the screen / page real estate available.

I have a primary chart which takes up a significant amount of space with some redundant space. I would like to plot a smaller chart or set of charts here.

I can use nested gridspecs as described on the matplotlib gallery and reposition the subcharts but not overlapping charts.

Taking example plots from QuantStrat, I can generate separate charts or modify the plots using gridspecs to create a tiled chart, but I am not able to achieve the following:

Is this possible using matplotlib or seaborn?
