Show conditional data in chart based on dynamic dropdown

Hi all,

I want to show performance data in a radar chart based on a choice the user makes. This choice comes from a dropdown menu with dynamic data where the user chooses from which ‘type of performance’ he wants to see his own data.

The user creates his own ‘performance type’ and when he completes a form this performance type is linked all performance measures within the database.

I want the user to select the ‘performance type’ and that the radar charts shows the data from that particular performance.

So for example; the user follows multiple different college courses (this is the performance type) and per course they accumulate multiple grades. I want them to select the course and the radar chart must show the corresponding data to that course.
