title: Python Quiver Options

  <p>I am solving a lid-driven cavity flow problem.  For creating the figure, I chose Python because it was the only language I know that has such a feature.  For the figure, I have to plot streamlines and vector arrows.  See the figure.</p>
  
  <p>Here is the line of code in question: <code>plt.quiver(x, y, u, v, color='black', headwidth=1, scale = 10, headlength=4)</code></p>
  
  <p>My problem is the size of the black vector arrows, not the blue streamlines.  I would like to have larger vector arrows with less arrow density.  Is there anyway I can do this in Python?  I have not seen this elsewhere.</p>
