I'm writing some data acquisition software and need a gui plotting library that is fast enough to do realtime updated graphs. I've been using Nplot which is pretty good for a free library, but I'm wondering if there are any better libraries (preferably free or cheap).

有这个好的帖子的这里和此处。我也用NPLOT在我们的最后一个项目，因为它更容易使用。

There's a good post about this here and here. I have also used NPlot in our last project since it's easier to use.
