Graph is not compiling right
I'm trying to add a graph to my dashboard and it's not working.
I have a Vehicles table, Maintenance table. I want to be able to show the Total Amount spent on each vehicle this month, this Qtr, this Yr. In the maintenance table, I have maintenance Date, Amount. It's linked with _fk_vehicleID. Will I need a radio button for this month, this Qtr, this Yr.
