title: ChartJS: Change the positions of the tooltips
body: <p>I have a problem with ChartJS: I need to use a Polar graph for my project and I have to show this graphic in a PDF.</p>
  
  <p>I also need to display the tooltips without hover. The problem is that these tooltips are at the center of each data.
  I want this specific one to be found outside of the graph. I modified the Chart.js a lot and now I have:
  <img src="https://i.stack.imgur.com/FoLtM.png" alt="tooltips"></p>
  
  <p>Unfortunately when the labels are long, the display is not good:

  <p>My method is not good. Has someone already managed to display tooltips outside the circle?</p>
