Now I actually come to look at this, it doesn't look as obvious as I was expecting.
The NDataGrouping Classify method you can override seems to be putting the input data into the levels, which must have been defined elsewhere, but where? Also what is the ClassCount parameter for? I don't understand how this all hooks up. I was hoping that I could just set the bounds of the levels somewhere and the classification would be done by existing Nevron code.
Thanks
