Gabor, Thanks a ton for your insights.
Two questions - Here is the code I tried to run: z <- with(airquality, zoo(cbind(Wind, Temp), Month + (Day - 1)/31)) plot(z, ylab=c("Wind (mph)", "Temp (Deg F)"), col=c("royalblue1", "red3"), xlab = c("Month Index", col="dark red")) grid() The grid does not appear to fit within the x-axis and y-axis limits, and also the Month Index text appears to be corrupted. Is there a way to fix this? Thanks again for the insights. --- On Wed, 8/5/09, Gabor Grothendieck <ggrothendi...@gmail.com> wrote: > From: Gabor Grothendieck <ggrothendi...@gmail.com> > Subject: Re: [R] Stacked plots with common x-axis and different y-axis > To: "Jason Rupert" <jasonkrup...@yahoo.com> > Cc: R-help@r-project.org > Date: Wednesday, August 5, 2009, 8:09 PM > Try this: > > library(zoo) > # ignore the fact that months have different lengths > z <- with(airquality, zoo(cbind(Wind, Temp), Month + > (Day - 1)/31)) > plot(z) # each on separate plot stacked above each other > plot(z, screen = 1) # both on same plot > > library(lattice) > xyplot(z) > xyplot(z, screen = 1) > > ?plot.zoo has examples of using two y axes on the same > plot > > > On Tue, Aug 4, 2009 at 5:33 PM, Jason Rupert<jasonkrup...@yahoo.com> > wrote: > > Is there a place that shows how to create two plots > that are stacked on top of each other where they share a > common x-axis scale, but have differnt y-axis scale? > > > > Say have the following data: airquality > > Stack plot(airquality$Day, airquality$Wind) on top of > plot(airquality$Day, airquality$Temp). > > > > I am interested in stacking the two on top of each > other with no seam, or plotting the two lines with two > different y-axis scales on the same plot. > > > > Thanks for any feedback and insights. > > > > ______________________________________________ > > R-help@r-project.org > mailing list > > https://stat.ethz.ch/mailman/listinfo/r-help > > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > > and provide commented, minimal, self-contained, > reproducible code. > > > ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
