I think it is just that you have to modify the graph settings to match what happens to the data source - and there's no handy way to convert existing history. But, if you are interested you should probably ask on the OpenNMS list where someone who knows what they are doing might answer. There are a lot of people using it in large-scale setups.
It is a lot easier to try OpenNMS than it was a few years ago - now there is a yum repo that basically 'just works' with Centos, and there's quite a bit of development work happening on it.
Added to my list of things to check out, at least this time I won't forget about it again. At this rate not till sometime early next year.
