noise <- matrix(runif(1000) + runif(1000 * 1000), nrow = 1000)
rownames(noise) <- sprintf("Row%d", 1:nrow(noise))
colnames(noise) <- sprintf("Col%d", 1:ncol(noise))
noise.colors <- chmNewColorMap(c(0, 1, 2),
  c("green", "black", "red"),
  missing.color = "yellow"
)
layer <- chmNewDataLayer("Noisy Data", noise, noise.colors)
