How can I represent 4 dimensional data in 3 dimensions(RGB) or 2 dimensions(XY grid)?

Anyway, it depends on what technology we're talking about.It sounds like you would need a 3d scatter chart with your fourth dimension being a selection control such as a slider that changes the time. You could use WPF w/ silverlight if you want to display it on a site but I'm sure a variety of technologies can be used to get the same result. You'll need to modify most common solutions to get the similar colors according to position.

Statistical algorithms like k-means is usually suited for clustering data together.

3d scatter is good except I want this to produce graphs for a paper and 3d graphs don't really make good representations on a 2d statis surface, I was hoping I could get just convert 4d info to 3d while keeping their relative values correct – iteratorr Jun 16 '10 at 5:03 I don't see how this is a programming question. Can you explain the data types of each dimension? Can you explain what technology you plan on using to implement this data display?

How about the ranges of each dimension. When I think of 4d data, I think of something like the position of stars over a period of time(1d = x, 2d = y, 3d = z, 4d = time). – James Santiago Jun 16 '10 at 5:53.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
