title: Plot marker at one point instead of start and end point in Python matplotlib
body: <p>I have a graph made up of lines with markers, however, I'm getting something that looks like this:<a href="https://i.stack.imgur.com/ejOlt.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ejOlt.png" alt="enter image description here"></a></p>
  
  <p>I was wondering if there was a was to get the marker plotted at only the start point of the line rather than both the start and the end?</p>
  
  <p>I can't seem to find anything on this anywhere so hopefully someone can help me!! Thanks in advance!</p>
