title: Excel: overlap bars of bar graph tool
body: <p>I would like to make a bar graph similar to a <a href="http://www.mrexcel.com/articles/timeline-chart-in-excel.php" rel="nofollow noreferrer">Gantt Chart</a> (see figure)</p>
  
  <p><img src="https://i.stack.imgur.com/V4ZWx.png" alt="Gantt chart"> </p>
  
  <p>but <strong>only showing one row, with every bar overlapped with the others</strong>. I want to do this supposing that I have non-overlapped periods, and the final figure is only one row with several red periods.</p>
  
  <p>How can I do it?</p>
  
  <p>Thanks.</p>
