Hi, I have a dataset which includes monthly data for 17 years. I want to be able to see the monthly data behavior for the period of all 17 years. What my data looks like: http://r.789695.n4.nabble.com/file/n4162534/data.jpg I would like to represent the data in a graph such as the one below: http://r.789695.n4.nabble.com/file/n4162534/Untitled-2.jpg Any help would be appreciated.

Your data set is not reproducible from an image (use dput() on your
next post to give us a taste of your data) but I'll hazard it's a ts
class object. If so, try this:
X <- ts( sample(500, 204), frequency = 12, start = 1995)
plot( rep(1:12, 17), X, col = rep(1:17, each = 12), xaxt = "n", xlab
"Months", pch = 20)
axis(1, at = 1:12, label = month.abb, padj = 0)
legend("bottom", pch = 20, col = 1:17, label = 1995:2011, horiz =
TRUE)
as a start. You can add the grid lines with (among others) the abline
function's h argument.

Sorry about that, new to posting here! Your code was extremely helpful, and
tweaking it a bit gave me the output I was looking for:
plot( rep(1:12, 17), pox, col = rep(1:17, each = 12), xaxt = "n",
ylab="Reported Cases",xlab "Months", pch = 20,
main="Monthly Trends of Chickenpox")
axis(1, at = 1:12, labels = month.abb, padj = 0)
legend(8, 28000,c("1993",
"1994","1995","1996","1997","1998","1999","2000",
"2001","2002","2003","2004","2005","2006","2007","2008","2009"),
inset=.05,
title="Years",
c(1993:2009), pch=20, horiz=FALSE, cex=.7)
Apparently there aren't enough colors for each year to have it's own
individual color, but I think I can live with that. Thanks again!
