How to figure out percentage change in time series?

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?

HUH? A 10% increase in A would cause a 15% increase in A? So is this inflation? Are you an economist? Must be voodoo economics in action.

I think you need to think more clearly about exactly what you want to do, and then explain yourself. CLEARLY.

To better understand I attached a figure. please see.

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().

Just for example I wrote -20 to +20. here I attached a figure. I want to plot similar type of figure.
