As suggested here, the way to be able to make a plot with two y axes is with
Overlay does not produce a graphics object which has many complications, the most basic one is, the plot cannot be resized.
When I try to do
on the code from the link above, I get a nicely pink, yet empty rectangle.
So, is there any way, to make this work as I assume
Overlay is just a very dirty way to produce to axes plots. I have read in some post that
Export should work with
Overlay objects but still, sometimes one just needs to play with the graphics in the GUI.
Also, is there any official Wolfram suggestion how to plot a two axes plots?
