       For your convenience some of the commands are explained
       here by using detailed examples. They are not always cut-
       and-paste ready because comments are intermixed with the
       examples.

       Depending on your needs you can do this in two ways:

       +o   Offset the data, then graph this

               DEF:mydata=my.rrd:ds:AVERAGE

           Note: this will also influence any other command that
           uses "data"

               CDEF:data=mydata,100,+
               LINE1:data#FF0000:"Data with offset"

       +o   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

       rrdgraph gives an overview of how rrrrddttooooll ggrraapphh works.
       rrdgraph_data describes DDEEFF,CCDDEEFF and VVDDEEFF in detail.  rrd-
       graph_rpn describes the RRPPNN language used in the ??DDEEFF
       statements.  rrdgraph_graph page describes all the graph
       and print functions.

       Make sure to read rrdgraph_examples for tips&tricks.
