title: how to add a background that display "no data" on Canvas using ChartJS?
body: <p>I would like to add a background with text saying that there is no data available if it's the case, using ChartJS V2.9.3 .</p>
  
  <p>For example, I would like to go from this (empty canva) :
  <a href="https://i.stack.imgur.com/1BpEb.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1BpEb.jpg" alt="empty canvas"></a> </p>
  
  <p>To this (background color with text display) :</p>
  
  <p><a href="https://i.stack.imgur.com/81VAF.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/81VAF.jpg" alt="no more empty background"></a></p>
  
  <p>Do you have any suggestions for doing that ?</p>
  
  <p>Thank you in advance</p>
