Hello, I need help using pie grading a classes average grade.
Here's what I've got : grade.png
When using pie, I got this : Screen Shot 2015-12-24 at 12.15.29.png
I need something like this : Screen Shot 2015-12-24 at 12.23.50.png --
this chart means that 12% of the grades are "1" , 18% - "2" , 18% - "3" etc.
Hope you understand what I want, sorry for my English.
