Re: [R] Superimposing 2 curves on the same graph with par(new=TRUE)

Because the range is so different between the two series, I'd suggest using log=y, ylim=c(500,2) Clint BowmanINTERNET: cl...@ecy.wa.gov Air Quality Modeler INTERNET: cl...@math.utah.edu Department of Ecology VOICE: (360)

[R] Superimposing 2 curves on the same graph with par(new=TRUE)

Dear R-Experts, I try to superimpose/present 2 curves/plots on the same graph. I would like the result/graph to be readable. For that, I use the par(new=TRUE) argument but on the Y-axis there is a superposition of writings and the Y-axis becomes unreadable. How can I solve this problem ? Here

curves on the same graph with par(new=TRUE) ... and that gives you a double ordinate plot, a staple of misleading statistics. Let me give you an analogy: Imagine you are on a chemistry mailing list and someone asks about the proper way to mix aluminum powder with fertilizer. Of course

Re: [R] Superimposing 2 curves on the same graph with par(new=TRUE)

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

Re: [R] Superimposing 2 curves on the same graph with par(new=TRUE)

Here is how: plot(Date,MORTSFr,type=l, ylim=c(0,max(MORTSFr))) points(Date,MORTSBu,type=l,lty=2) If you don't use the same scale for the two plots, you are probably misrepresenting the data. If you want to plot relative change, normalize the data before plotting. norm - function(x) {(x -

... 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

Agreed--I neglected to add the secondary y-axis (shouldn't hit send so fast.) Clint BowmanINTERNET: cl...@ecy.wa.gov Air Quality Modeler INTERNET: cl...@math.utah.edu Department of Ecology VOICE: (360) 407-6815 PO Box 47600
