[R] Fwd: Re: Graph color

[baptiste auguie]

Hi,

Try this,

x <- seq(0, 10, len = 100)
y <- jitter(sin(x), 1000)

old.par <- par()
par(bg=grey(0.5))

plot(x, y, new = TRUE, t = "n")
lims <- par("usr")

plot(x, y, col = 1,
  panel.first = {
    rect(lims[1], lims[3], lims[2], lims[4],
      col = "lightblue") })

HTH,

baptiste
