I am trying to make a plot where each data point gets plotted with a user-defined color, i.e., one set of x-y pairs, with each point having a different color, and not, e.g., 3 sets with 3 different colors. If anyone has tried this, I''d appreciate seeing how it''s done. I have tried to make something analogous to the way "January Pie Sales" (from the demo("graphics") set) was done, using ''plot'' instead of ''piechart'', but only the first color in the list gets used. Thanks for any useful advice. M. A.

Hi, Perhaps try the c() parameter. e.g.> x <- 1:10 > # plot(x) > plot( x, col = c( "red", "blue", "black", "cyan", "green", "yellow" ) )It was only an example, I haven''t specified 10 colours for the 10 x values (well it is hard to think 10 colours at once), but you get the idea :-) Cheers, Kevin ---------------------------------------------- Ko-Kang Kevin Wang Head of Statistical Analysis Division Software Developers'' Klub (SDK) University of Auckland Auckland New Zealand -----Original Message----- From: owner-r-help at stat.math.ethz.ch [mailto:owner-r-help at stat.math.ethz.ch]On Behalf Of M.

What are you doing that''s different?

I had intended this for color mapping on something like persp(), but it would easily provide spatially distributed colors on a scattergram if that is what you are trying to do.
