Thanks to all who have replied.

I must apologise for the mess I made of asking the question, looking 
back I did not make myself at all clear, and congratulation to Terry 
for seeing through the confusion and picking up correctly on what I 
was trying to ask.

His last paragraph, below, sums up perfectly what I am trying to 
achieve. It is an electronic version of printing off the two 
individual plots onto clear actetate and then overlaying them 
physically, in which case the gains of the outer rings will be different.
