I used ?image function to do that, like below :

require(grDevices) # for colours
x <- y <- seq(-4*pi, 4*pi, len=27)
r <- sqrt(outer(x^2, y^2, "+"))
image(x, y, r, col=gray((0:32)/32))

However my next problem to add a color pallet for color description [as shown in following link]. If anyone here tell me how to do that, it will be good for me.

Can anyone here please tell me whether is it possible to produce a chart displayed in http://www.datawolf.blogspot.com/ in R for visualizing multivariate time series? If possible how?
