Error nested axes pgfplots

[jellinge]

Dear all,

I am trying to convert the following Python plot to Tikz:

Without the detail (created by using ax.inset_axes(...)), everything works perfectly fine. However, with it I cannot compile my document anymore because of a pgfplots error:

Package pgfplots Error: Sorry, nested axis environments are not supported. Please move the inner axis environment below \end{axis} and use alignment options (for example named node
s, see manual) to place it at the desired position.

The export works just fine: example.zip

Is there a way to fix or circumvent this?

Best
Joe
