title: Matplotlib - How to remove a specific line or curve
body: <p>I want to remove a specific line in a plot of multiple lines. Bellow is a given example which is not sufficient for me because it removes only the last plotted line and not the line that I want to remove. How can I do that? How can I address a specific line(by name, by number, by reference) throughout the program and delete that line?</p>
  
  <pre><code>self.axes.lines.remove(self.axes.lines[0])
  </code></pre>
