title: Suggestions to plot overlapping lines in matplotlib?
body: <p>Does anybody have a suggestion on what's the best way to present overlapping lines on a plot? I have a lot of them, and I had the idea of having full lines of different colors where they don't overlap, and having dashed lines where they do overlap so that all colors are visible and overlapping colors are seen.</p>
  
  <p>But still, how do I that.</p>
