title: Mathematica plot vector field from data file
body: <p>I am trying to plot a vector field from data file. I can put the data into file in any way, but for now data file contains information in this form:</p>
  
  <p>x y Fx Fy</p>
  
  <p>where Fx and Fy are x and y components of a vector.</p>
  
  <p>Any ideas how to plot it?</p>
