I would like to create a PIE chart only using the percentage for the ID's who are all completed how many number of certificates .
For example ,
ID No of Courses_completed
Likewise I have 1000's of ID . Here I need to find out from total ID , 30% of them completed 2 courses , 40% of them completed 3 courses, 15 % of them completed 1 course, 15% of them not attended any course in PIE chart view. Kindly help to acquire this.
