title: Change color limits with quiver in matplotlib?
body: <p>How should the syntaxis be for changing the limits of the color range when plotting with quivers in matplotlib? I have the following code:</p>
  
  <pre><code>PyPlot.ion()
  xlim(1, 64)
  ylim(1, 64)
  flechitas = quiver(x, y, EFx, EFy, sqrt((EFx.*EFx+EFy.*EFy)),
          pivot="middle", cmap="Blues")
  cb=colorbar(flechitas)
  </code></pre>
  
  <p>Which produces an adecuate image but uses automatically detected range for the 5th argument (the color). In the <a href="http://matplotlib.org/api/pyplot_api.html?highlight=quiver#matplotlib.pyplot.quiver" rel="nofollow">manual of matplotlib</a> it says that I can use the <code>clim</code> keyword but if I put it inside the arguments or outside, after the xy limits, I get an error indicating that I must create an image first, with imageshow. If I do that, then I get a more obscure error, an <code>AssertionError()</code>. My matplotlib is 1.3.1.</p>
