...s), but I haven't been able to figure it out for two different types of plots. Below is my test case: library(ggplot2) library(gridExtra) #generate test precipitation data year<-c(2000,2001,2002,2003,2004) precip<-c(46,100,80,74,20) yp<-data.frame(year, precip) #generate test fecal coliform data year2<-c(2000,2000,2000,2000,2000,2000,2000,2000,2000,2000, 2001,2001,2001,2001,2001,2001,2001,2001,2001,2001, 2002,2002,2002,2002,2002,2002,2002,2002,2002,2002, 2003,2003,2003,2003,2003,2003,2003,2003,2003,2003, 2004,2004,2004,2004,2004,2004,2004,2004,2004,2004) fc<-sample(1:1000, 50) y...

...and one of the graphs is a bar plot of 'Z' scores. On the bar plot I am using the following line to plot some results barplot (zb[,c("ZBW")], ylim = c(-6,6), names.arg=zb[,c("LabNo")],xlab="Lab Code Number", cex.names = .5 , axis.lty=1 , main = " Total Coliform ") What I would like to do is move the xlab parameter to sit on top or on each bar and not on the x-axis at y=0. Any help would be appreciated. Thanks Steve [[alternative HTML version deleted]]
