Having a calendar counting weeks

Hi, i'm actually having some headache using matlab... i have a vector that can be 3*(52*x) where x is the number of year that i want to work with. As you can guess in this vector i have a 3 type of informations (actually that's a workload) for all 52 weeks of the year (1 year is approximately 52 weeks). Then i want to plot it like a bar graph where in the y-axis we would find the workload in [worker per week] and i want the x-axis divided per week but it has to reset to 1 when it's over 52 week. Can we make the tick of x-axis reset as i mentionned ? i hope i've been clear enough. Thank you.
