Here is a better indication on what I am trying to do with a 2d plot: Matrix: 1 2 6 3 5 4 8 9 5 I need the x axis (column #1) scaled from 1 to 8 I need the y axis (column #2) scaled from 2 to 9 At (x,y) = (1,2), I need a point plotted of color value = 6 (darkest) At (x,y) = (3,5), I need a point plotted of color value = 4 (lightest) At (x,y) = (8,9), I need a point plotted of color value = 5 (middle) Thanks again!
