If you know the number of points along the x-axis in advance, one way would be
to specify the number of x-axis intervals with the "coord" keyword and then
make the week numbers tick labels.  For example if you have 52 points on the
x-axis:

coord x 0,52
ticks bot out at 1 "8801",2 "8802" ...

or whatever interval you want between ticks.  I know this is messy, but nothing
else comes to mind.
