title: How to mark event in the devtools graph?
body: <p>I want to &quot;mark&quot; a step in performance tab in chrome devtools.</p>
  <p>So I use <code>console.timeStamp</code> to do so. but this function just add a marker within the graph (as you can see the small rect under the tooltip).</p>

  <p>What I expected to be is create it in the top of the graph.</p>
  <p>Something like this (I mark it by red arrow):
  This small rect is the <code>console.timeStamp</code>, as I want.</p>
  <p>So there is a function that mark the way I describe?</p>
