Hi all:
Is there a plot tool to use different color indicates difference
magnitude of data?
The plot is in the attachment.
Many thanks.
No sure what you want exactly as there is no attachment here.
Here are an example of what can be done:
x <- 1:128
y <- rnorm(128, 10, 2)
z <- x+y
nbcol <- heat.colors(128)
# standardize z to be from 1 to 128
zcol <- ((z-min(z))/(max(z)-min(z)))*127+1
# different examples
plot(x, y, col=nbcol[zcol], pch=".", cex=10, bty="n")
plot(x, y, col=nbcol[zcol], pch=".", cex=zcol/10, bty="n")
plot(x, y, col=nbcol[128-zcol], pch=".", cex=10, bty="n")
Sincerly
Marc
