Here's an example:
http://stats.es.net/serviceTest/graphWidget.cgi?url=http://anl-pt1.es.net:8085/esmond/perfsonar/archive&dest=198.129.254.22&source=198.124.252.117&url=http://anl-owamp.es.net:8085/esmond/perfsonar/archive&dest=198.129.254.22&source=198.124.252.97&url=http://anl-pt1.es.net:8085/esmond/perfsonar/archive&dest=198.129.254.34&source=198.124.252.117&url=http://anl-owamp.es.net:8085/esmond/perfsonar/archive&dest=198.129.254.34&source=198.124.252.97

There are some limitations to this approach -- it doesn't like it more than 
one host has data for a given type. For example, if more than one host has 
Throughput data it will not handle it nicely, as far as I recall.

This derives from esnet's Dashboard -- clicking around you can find other 
examples with multiple hosts.

Hope this helps.
