title: Charting duration of time
body: <p>I'm fairly certain from the reading I did prior to this post that a Gantt chart is what I will need to create, however I don't know if that is the correct route or not.</p>
  
  <p>Need to plot data of start and end times as one unit on an Excel chart, with date on the Y-axis and hour of day on the X axis.</p>
  
  <p>The format of the start and end times are Excel numbers which is adding another curveball into the mix.</p>
