Dear all:
I am trying to center labels on my plot with not much success. I have tried
text(), mtext() but it's not working. I think I am using the wrong function
for my task.
Any help will be appreciated.
My working codes.
axis(1,
at=c(1,2,3,4,5),font.lab=2,cex.axis=1.5,cex.lab=3,label=c("W0","CWH2","CWHmc","CH2","CHmc")
,text=c(1.5,2.5,3.5,4.5,5.5))
Many thanks in advance
YA

Hello, Your working code needs a plot first: plot(1:5, xaxt = "n") And there's no 'text' argument to axis(). As for the centering of axis labels, they're centered on my graphics device.

The bars in the standard "barplot" function are not centered on integer values, but the centers are returned from the function: barpos<-barplot(...) axis(1,at=barpos,...) Is this the problem you are having? Jim
Thanks Jim and Rui. My apologies, i did not give enough info on my plot. I am using : plot(x,y) for a line plot. I want to center the labels on the x-axis for each tick.

Have a look at the staxlab function in the plotrix package. Jim
