Plot 2D - with third argument (colorbar)
in [Matlab]

From: Goran Gašparac on 28 Jul 2010 09:52 Hi there, I have 3 vectors, 2 of them represent x,y point coordinates, and the third represents the appointed values for those points. Is it possible to plot those x,y coordinates, e.g. plot(x,y,'.') and then add a colorbar which will be connected to those values, where the colorbar is defined by the third vector. Result will be a plot of many dots with different colors where every color represents a value which can be read from colorbar. Cheers, Goran
