while this is possible, I am not usre if you really want to do that.
mrtg does not support different y scales (e.g. one for ms and one for %).
smpkeping is definitly the tool, and worth to install!

for mrtg-ping-probe yoiu can select which values are returned, e.g.

	mrtg-ping-probe -p avg/loss <target-host-name>

would return average round trip time and packet loss.

If you RTT is high, e.g. 500 ms, your packet loss will not really be
visible well in the graph (0 .. 100) %.

I'd recommend to keep the graphs separate, or even better, install
smokeping.  http://oss.oetiker.ch/smokeping/

Hope this helps
