Adding a poller to just one node

Hi there,

Two questions (NPM 1.4.1).

How can I add a chart item to just one node?  When I click Customize Page it edits the page view for all nodes.

I have a poller (APC SmartUPS Universal Device Pollers) but when I add a Customer Poller chart, it only displays one piece of data at the time.  How can I add a one chart with all the data from multiple pollers?

Thanks

Shane
