Hi, I have a data set of points which are represented by 3 variables x,y,z where x is the position of the point on the x-absciss and y on the y-absciss. Each of my points has a value z, which I want to be displayed as follows: the more z is high, the more the color on the map is dark. How can I achieve this ? Thanks for your help -- View this message in context: http://n4.nabble.com/Absolutely-No-idea-how-to-plot-my-Sp...
