I have only just discovered the joys of the dotchart (since I am reading William Cleveland's -- Sean Carmody The Stubborn Mule http://www.stubbornmule.net http://twitter.com/seancarmody [[alternative HTML version deleted]]

...option in the office! I have been searching the archives on this topic to no avail (although I can vouch for the perspicacity of my choice of search terms), so any help would be greatly appreciated!

I have been experimenting with various approaches to plotting (irregular) time-series with reasonable success. One thing I have been able to do is change the number of tick marks on the axis. Consider the following simple example: > x <- as.data.frame(matrix(ncol=2,nrow=500)) > names(x) <- c("dates","values") > x$dates <- as.POSIXct(Sys.time()+1:500*86400)

Does anyone have any ideas about how you could use R to produce a fancy area plot like this one in the NY Times? http://tinyurl.com/6rr22g Regards, Sean, [[alternative HTML version deleted]]
