Good afternoon, I am looking for a way to do a scatterplot of 4 values summing to 1 inside a 3D symplex, i.e. an equilateral pyramid. With the function triax.plot I can do that with 3 values summing to 1, but I can't find an equivalent with an extra dimension. Thanks to whoever can help me! Best, Gabriele Esposito

Might be able to look at it more closely tomorrow. Jim
