The tasks are generated through a sql query in another php. The 'start' and 'end' date of each task are loyal to the database. What i'm trying to do is to plot each task in a 'different line'. If one task from Jean goes from Jun, 10 until Jun, 20 and another task from Jean goes from Jun, 15 to Jun 25, the second task is plotted above the end of the first one, and it's not easy to see when the first one finishes.
I attached a image of what I'm looking for, but instead of using 'planned' and 'actual', I'm using the 'j' variable to name each task for a different person. The first task for Jean is named '0', the second is named '1' and so on... and that repeats for every responsible
