I'd like to have a line graph of my users' total user points in time on their profile page. Users shouldn't be able to modify the graph: it should simply graph the user points from the day the user registered until today. I'd like to use the Charts module, but I don't know how I can provide the necessary data (date and daily total points).
Perhaps it's also handy to mention that the profile pages on my website have been overridden with "user_view" (see: How to create a profile page?) into a panels page.
How can I achieve this?
Edit: I tried to find a solution, using Field Collections as @Felix Eve suggested in his answer. I've successfully added a Field Collection to my users, but I'm still stuck at these points:
- Save the userpoints at the end of the day as a field collection item for all users.
- Graph the userpoints in a Chart.
Solving these problems, solves this problem aswell.
