[rrd-users] Time axis: how to print date instead of week number

  Hi Sven.  You're looking for the --x-grid parameter in the 'rrdtool
graph' command.  See:

   For example, you might use something like:
--x-grid DAY:1:DAY:7:DAY:2:86400:%d

   will print 1 minor grid line (thin vertical line) every day, a
major grid line (thicker vertical line) every 7 days, so the space
between any two vertical grid lines is 1 day's worth of data.  It will
also print the day of the month (numeric, since I specified %d) every
2nd day, and will centre that label beneath the space for that day
(the 86400 parameter controls this).  I specified every 2nd day
because doing it for every day might clutter your x-axis labels.
  Check the docs though, as there are plenty of nifty things you can do with it.
