I don't think this is built in.  VDEF would be a nice mechanism to get it,
but so far nobody programmed it and nobody sponsored me to do it.

No problem. As always:

Get the number (e.g. using rrdtool dump), then use it in your rrdtool
graph command inside the GPRINT command, just like you would print "hello,
world".

Yes, this means calling rrdtool twice.
