title: Remove a graphs label with for loop in Python
body: <p>I have a graph that displays this  <strong><a href="https://i.stack.imgur.com/rYzkv.jpg" rel="nofollow noreferrer">https://i.stack.imgur.com/rYzkv.jpg</a></strong>
  when a colored line (chemical element) is deleted, I want my corresponding annotated label to be deleted as well. I have it set up by appending the annotation labels to a list, if the label is not in any of the lines, delete the label that doesn't have that line showing.</p>
  <p>The annotation list does in fact update to show the remaining labels after deleting the lines, but with tons of Attribute errors in between. And still the labels aren't being removed. How do I fix this using this idea?</p>
  <p><em>P.S. The button that deletes the chemical line are in other files that I would rather not share. Over 20 files with different classes. So I hope to solve it using this method</em></p>
