-
-=head1 SYNOPSIS
-
-B<rrdtool graph /home/httpd/html/test.png --img-format PNG \>
-

-=head1 DESCRIPTION

-by using detailed examples. They are not always cut-and-paste
-ready because comments are intermixed with the examples.

- CDEF:ds1bits=ds1,8,*
-
-Note: 10 spaces to move text to the right
-
- COMMENT:" "
-
-Note: three times size == 11 chars, "###.## xBps"
-
- COMMENT:"Maximum "
- COMMENT:"Average "
- COMMENT:"Minimum "
-
-Note: last line contains new-line character
-
- COMMENT:"95th percentile\n"

-
-=head2 Offsetting a line on the y-axis
-
-Depending on your needs you can do this in two ways:
-
-=over 4
-
-=item *
-
-Offset the data, then graph this
-
- DEF:mydata=my.rrd:ds:AVERAGE
-
-Note: this will also influence anything that uses "data"
-
- CDEF:data=mydata,100,+
- LINE1:data#FF0000:"Data with offset"
-
-=item *
-
-Graph the original data, with an offset
-
- DEF:mydata=my.rrd:ds:AVERAGE
-
-Note: no color in the first line so it is not visible
-
- LINE1:100
-
-Note: the second line gets stacked on top of the first one
-
- LINE1:data#FF0000:"Data with offset":STACK
-
-=back
-
-=head2 Time ranges
-
- Last four weeks: --start end-4w --end 00:00
- Januari 2001: --start 200101010000 --end start+31d
- Januari 2001: --start 200101010000 --end 200102010000
- Last hour: --start end-1h
- Last 24 hours: <nothing at all>
- Yesterday: --end 00:00
-
-=head2 Viewing This week and last week together
-
- --end now --start end-1w
- DEF:thisweek=router.rrd:ds0:AVERAGE
- DEF:lastweek=router.rrd:ds0:AVERAGE:end=now-1w:start=end-1w
-
-shift the data forward by one week (604800 seconds)
-
- SHIFT:lastweek:604800
- [ more of the usual VDEF and CDEF stuff if you like ]
- AREA:lastweek#0000FF:Last\ week
- LINE1:thisweek#FF0000:This\ week
