-An example can be found in the plugin "exim_mailstats" - the plugin graphs
-the number of mails that have been received and delivered locally by the
-system. The values are gathered and stored in a "mails per second"-format.
-On most systems, this is a bit odd, since you'll get numbers like "300
-ultramail per second". :-) A cdef is therefore defined to adjust the
-values into "mails per minute" instead - a much more sensible and readable
-number. To do this, the value is just multiplied by 60. The configuration
-line looks like this: <code>received.cdef received,60,*</code> . In
-"normal" math, you'd just say "received=received*60".

-For a more thorough definition of RPN, take a look at the man-page for
-"rrdgraph".

+<h3>Q: Can I get a graph to show percentages instead of regular values?</h3>
+<p>
+You can modify a graph with two data fields to a percentage view with
+the following cdef (gotten from Nicolai Langfeldt). It uses two field
+names, "hit" and "all", with "hit" being the field you want in
+percentages of "all".
+<code>
+hit,all,1,all,0,EQ,IF,/,100,*,UNKN,all,0,EQ,IF,UNKN,all,UNKN,EQ,IF
+</code>
