Initial Comment:
Hello,

There is a news on the project page:

"24 August 2005 Dominic Thuillier has made some very cool modifications to NPlot that allow adding new data points to LinePlot's without refreshing the rest of the plot. This is functionality that he needed but couldn't find in any of the commercial charting controls. I'm considering this a "polishing" addition and I'm including it before the 1.0 release. I'm about halfway through adding it in. My changes are basically a generalised version of Dominic's implementation. As part of this I'm thinking about improved support for data binding (over the whole library). I'm also further progressed on the modifications mentioned in the last post. These are the three improvements to look forward to in the next release."

Have these modifications dropped out in current release?  At the moment the chart is not changing when I add data points to the binded source.

To solve this you can make a new data assignment of the data source for each new data point. In this case the library performance(WinForms) is very slow. I'm thinking of data sources with 20000 data points and multiple updates per second.

Yes, this work did not make it into the current version.

I am currently working on optimization work.
