Hi, If he wants the two sets of data plotted on the same y axis scale, with the range of the y axis adjusted to the data, an alternative to the use of plot() and points() is:
matplot(Date, cbind(MORTSFr, MORTSBu), type = "l") See ?matplot Regards, Marc Schwartz > On Mar 23, 2015, at 12:04 PM, Boris Steipe <boris.ste...@utoronto.ca> wrote: > > ... which is exactly what he shouldn't do because now it the plot falsely > asserts that both curves are plotted to the same scale. > > > B. > > > > On Mar 23, 2015, at 12:34 PM, Clint Bowman <cl...@ecy.wa.gov> wrote: > >> Try: >> plot(Date,MORTSBu,lwd=2,lty="dashed",axes=F,xlab="",ylab="") >> >> >> >> Clint Bowman INTERNET: cl...@ecy.wa.gov >> Air Quality Modeler INTERNET: cl...@math.utah.edu >> Department of Ecology VOICE: (360) 407-6815 >> PO Box 47600 FAX: (360) 407-7534 >> Olympia, WA 98504-7600 >> >> USPS: PO Box 47600, Olympia, WA 98504-7600 >> Parcels: 300 Desmond Drive, Lacey, WA 98503-1274 >> >> On Mon, 23 Mar 2015, varin sacha wrote: >> >>> Dear R-Experts, >>> >>> I try to superimpose/present 2 curves/plots on the same graph.
