Hi All,

I need some help with adding text at the bottom of the graph (outside of
default outline of graph).

Say, I need to write "Month:   01     04" below each of the two years in the
following R code, something like this:

           _______________
           |                         |
           |         Plot          |
           |___  __________|
            1931          1932
Month:   01              04

# R code
require(lattice)
barchart(yield ~ year, data = barley,
   stack=TRUE,
   col="black",
   ylim=c(0,85)
)

Hi Peng,
Try using mtext:

mtext("Month:  01   04",side=1,line=2,at=0,adj=0)

You may have to adjust the last three arguments to get it in the correct position.

Jim
