The Underscore Archives

Dear [_],

I have a requirement to plot a large data set in several synchronised
channels (we're talking 100,000 + points per channel plot) and sooo
I've started the new year off by looking into filtering algorithms to
scale down the dataset to something more managable but maintain the
fine scale data structure for zooming purposes. It suddenly struck me
that this is exactly what a wave form viewer does, basically plot
millions of points of data very quickly and maintain any fine scale
artefacts(doesn't it?).

Anyone aware of any good tutorials on this or in an ideal world some
example code in C#? Been googling but as yet not found anything
suitable (i.e. easy to understand, free and with some example code).
Sounds like the sort of thing a million and one techies would program
in their bedroom :-)
