Hi Fang, An easy way of doing this is by:

I also want to get some similar graph, but the data is not time series data. Suppose here is my data one, I want a graph with x-axis is just the index(1:9). The graph plot all the variable A, B,C,D. So there should be 4 lines for each graph. For the A line, at each time point, the letter A should be on the line. And the same goes for the B line. A B C D > 8 4 9 8 > 7 5 4 7 > 6 8 4 4 > 3 7 6 2 > 5 1 8 5 > 6 4 7 1 > 2 8 3 4 > 1 2 4 8 > 4 3 1 9 So I add a name for each row rownames(one) <- c(1:9) z <- zooreg(as.matrix(one), start = 1, freq = 1) z <- aggregate(z, as.Date, tail, 1) plot(z, plot.type = "single", type = "o", pch = c("A", "B", "C", "D"), lty = 1:2) I get the plot, which I think it should be right. but the problem is that the x-axis still have month (Jan, ) on it and I didnot get "A,B,C,D" on my graph, is there any thing wrong? >From: "Gabor Grothendieck" <[EMAIL PROTECTED]> >To: "Bill Pepe" <[EMAIL PROTECTED]> >CC: r-help@r-project.org >Subject: Re: [R] Time series graphs >Date: Thu, 20 Sep 2007 14:15:54 -0400 > >Using plot.zoo in the zoo package try this: > >Lines <- "Bob.A Bob.B Tom.A Tom.B > Jan 8 4 9 8 > Feb 7 5 4 7 > Mar 6 8 4 4 > Apr 3 7 6 2 > May 5 1 8 5 > Jun 6 4 7 1 > July 2 8 3 4 > Aug 1 2 4 8 > Sep 4 3 1 9 >" >DF <- read.table(textConnection(Lines)) > >library(zoo) >z <- zooreg(as.matrix(DF), start = as.yearmon(as.Date("2007-01-01")), >freq = 12) z <- aggregate(z, as.Date, tail, 1) plot(z, plot.type = >"single", type = "o", > pch = c("A", "A", "B", "B"), lty = 1:2) legend("bottomleft", c("Bob", >"Tom"), lty = 1:2) > > > >On 9/20/07, Bill Pepe <[EMAIL PROTECTED]> wrote: > > I'm fairly new to S-Plus and I need to get this done quickly. > > Suppose I >have the following fake data below: > > > > There are two companies, call them Bob and Tom.
