I have time series values (monthly/annual/seasonal) of coefficient value (S) and A. I want to make a plot, where x axis (A) and y axis (S) limit will be varying between -20 to +20 in percentage. figure will demonstrate, If coefficient (S) is 1.5, than 10% increase of A would cause a 15% in crease in A. How will I make this figure?

I'm not sure now what you want. What do you want? You have the data (S and A), right? So just use plot() and let the axes adjust automatically. What's the problem?

Your figure did not get attached.

What's wrong with letting the axes determine the limits? If you want constant limits, then you can call xlim() and ylim() to set them in advance. Put "hold on" so that when you plot again, it will keep those limits. Or else call xlim() and ylim() with fixed limits after you call plot().
