Hello David, When I used the same ylim for both plots, I got what I need:
x = c(0,0,0,10,20,30) y = c(40,50,60,70,80,90) plot(x, type='o', ylim=c(min(x,y),max(x,y))) par(new=T) plot(y, type='l', ylim=c(min(x,y),max(x,y))) Thanks, Rebecca -----Original Message----- From: David Winsemius [mailto:dwinsem...@comcast.net] Sent: Friday, February 01, 2013 11:39 AM To: Yuan, Rebecca Subject: Re: [R] Range difference of plot two arrays in one plot On Feb 1, 2013, at 10:28 AM, Yuan, Rebecca wrote: > Hello all, > > When I tried to plot the following two arrays in one figure with the > following: > > x = c(0,0,0,10,20,30) > y = c(40,50,60,70,80,90) > plot(x, type='o', ylim=c(min(x),max(x))) > par(new=T) > plot(y, type='l', ylim=c(min(y),max(y))) > > Found that the first points and last points from those two arrays are > overlapping together, but the value 30 is not equal to 90.
