title: Gnuplot: coloring area inside uncertainty
body: <p>I have a bunch of 2D points, each point comes with an error in the x coordinate and in the y coordinate. I don't like how <code>with xyerrorbars</code> shows the points because these are measurement that will be more and more dense.</p>
  
  <p>I'd like if these points could form a colored surface, like these kind of plots:

  <p>Do you know if there's there a striagth forward way in Gnuplot?</p>
  
  <p>Thanks!</p>
