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.
