So I have two arrays, one representing my x values and one representing my y values. Lets call them
x = [2, 40, 5, 900]
y = [4, 8, 90, 20]
each of these arrays has a third quntity associated with them indicating the brightness at that point, lets call it
z = [10, 9 , 15, 14]
I want to plot the x and y points on a two dimensional axis and represent these z values as changes in color (darker colors for larger numbers). Any ideas? I am fairly stumped.
