Hi, Ravi,

How are you creating the legend? Here's a trivial example where you can add a cex argument to "auto.key":

library(lattice)
trellis.par.set(theme = col.whitebg())
xy <- xyplot(decrease ~ treatment, OrchardSprays,

              groups = rowpos, type = "a",
              auto.key = list(x = 0.2, y = 0.9,
                cex = 0.75, points = FALSE, lines = TRUE))

print(xy, pos = c(0.0, 0.0, 0.5, 0.5), more = TRUE)
print(xy, pos = c(0.0, 0.5, 0.5, 1.0), more = TRUE)
print(xy, pos = c(0.5, 0.0, 1.0, 0.5), more = TRUE) print(xy, pos = c(0.5, 0.5, 1.0, 1.0), more = FALSE)

HTH, --sundar
