Hi Tal, Thanks for your help.
I've had a look at the site, and what i wanted to do was to plot X and Y where X is a characters and Y is numeric. The problem I'm having now is that the X axis isn't characters but just numbers from 1 onwards and when i plot it, the data i have is in descending order which isn't shown on the graph. I have this at the moment: plot(1:nrow(dat),dat$Mean,type="b",xaxt="n", ylim=c(min(dat$lci),max(dat$uci)), xlab="",ylab="HR",) It gives me sort of what I want. It has the Y values in descending order, but it doesn't give me the text on the x axis and I was also thinking of plotting the upper and lower confidence intervals with a line connecting the two. I can add in the upper and lower CI values separately, but I don't know how to join the two together. -- View this message in context: http://r.789695.n4.nabble.com/How-can-i-draw-a-graph-with-high-and-low-data-points-tp2282524p2283194.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
