How to create following chart for visualizing multivariate time series
4 messages · Megh Dal, jim holtman, Henrique Dallazuanna
Try something like this:
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))
colors <- colorRampPalette(c('red', 'yellow', 'blue')) # create you
color spectrum
image(x,y,r, col=colors(100))

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.

library(lattice) levelplot(r, colorkey=list(col=gray((0:32)/32)), col.regions=(col=gray((0:32)/32)))

Hi Jim, i think you could not get my point. I did not want to put red-blue color there. I want to put a pallet which will describe the values of r. please have a look on following : http://bp0.blogger.com/_k3l6qPzizGs/RvDVglPknRI/AAAAAAAAAKo/itlWOvuuOtI/s1600-h/pairwise_kl_window60.png. Please see how a color pallate is added on the right side of this plot describing the value of red color, value of blue color etc. Is there any solution?
