[R] Scale of axis for two data sets

Well I have not spent a lot of time looking at the data , especially with what appeared to be a constant :) . It was not clear to me that they were the same units for one thing.
From my point of view (essentially total ignorance) if you have a situation where you have data plotted with the same set of units it's even dicier to use a two scale plot. You are just demanding too much of the reader to figure out which line is which and remember that the line attached to the right axis is 10^3 of the values of the left access.
My solution would probably be to just stack the two graphs one on top of the other , with the top graph having the 'higher' values. However it is a judgement call and also dependent on the discipline.
Anyway see the quick and dirty attempt attached to see what I am suggesting.

Hi,
Can't one y-axis be used ? Both 'Kbytes' and 'RSS' use the same unit.
Thanks,
Mohan

Still looks like a constant to me :) I think I see what you mean though. It's just that representation of the numbers in the email don't show any difference.
Personally I think I'd go with a two panel graph using par() rather than a double-axis graph if you can. Everything I have read about double-axis graphs is rather negative. However, I know they are standard in some disciplines.

It is not a constant but changes very slowly. Actually it should be like this.
Kbytes RSS rNo
2687188 1287532 1
2687188 1287532 2
2687188 1287536 3
2687188 1287540 4
2687188 1287640 5
2687188 1287640 6
Thanks,
Mohan

I am misreading something here I think. Why are you graphing against a constant?
