How to see the progress for an process instances

I want to know the progress for an process instance.

How can i get the progress?

As of now we can get the diagram for process instances. But Is there any way we can get the progress of our process instance in percentage terms?


On top of above info. ,
You need write a logic for percentage calculation, by counting total number of tasks that need to complete and with respect to uncompleted count tasks.
