Thanks a bunch, Coltrey! That works like a charm as well!
In summary, the code that solves both my queries is shown below: --------------------------------------------------------------- mdat <- matrix(c (-2.65,-3.7,-0.8,-1.4,-2.39,-1.12,-4.78,-4.9,-0.76,-1.56, 1.77,1.41,1.92,1.78,0.05,0.96,0.29,1.4,0.53,1.49, 1.4,0.35,1.65,2.14,1.88,2.75,1.86,0.32,2.96,2.28), nrow = 3, ncol=10, byrow=TRUE, dimnames = list(c("A", "B","C"),c ("S-1","S-2","S-3","S-4","S-5","S-6","S-7","S-8","S-9","S-10"))) barchart(mdat, groups=FALSE, layout=c(2,5), aspect=0.7, reference=FALSE, as.table=TRUE, main=list("Maintitle",cex=1), panel=function(x, y, ...) { colours <- character() colours[x < 0] <- 'red' colours[x > 0] <- 'green' panel.barchart(x, y, col=colours, ...) },par.settings=list(grid.pars=list(fontfamily="mono")), xlab="x-axis labels") --------------------------------------------------------- -Girish ======= On Jun 3, 11:20 pm, Coltrey Mather <r-h...@cowsgomoo.org> wrote: > No problem.
