  <p>I have 3 vectors of 315,000 elements each. X,Y, and Z. X &amp; Y are coordinates and Z is a value. I must plot the coordinates as points in a 2D graph, the Z is a color indicator at each coordinate of X and Y. I've tried the "scatter" command, but it extremely slow. Would anybody suggest a better way?</p>
  
  <p>thanks!</p>
