Show progression on timeline or Gantt


I did not find how to have a view where I can see the progression bar in a Gantt or a simple timeline view. For example, in the Gantt, I did not find a way to, instead of the status, simply show the progression of the task. The goal would be to have something like this :

This allows to see quickly if we are late or not : if the progression bar is before the current day, the task is late.

Can you please help me to achieve this ? As the progression is already there, it should be possible to simply show it in the diagram with a timeline I guess.

Thanks a lot,
