title: Matplotlib Plot Lines with Colors Through Colormap
body: <p>I am plotting multiple lines on a single plot and I want them to run through the spectrum of a colormap, not just the same 6 or 7 colors. The code is akin to this:</p>
  
  <pre><code>for i in range(20):
       for k in range(100):
            y[k] = i*x[i]
       plt.plot(x,y)
  plt.show()
  </code></pre>
  
  <p>Both with colormap "jet" and another that I imported from seaborn, I get the same 7 colors repeated in the same order. I would like to be able to plot up to ~60 different lines, all with different colors.</p>
