30 September 2006 It seems there is quite a lot of interest from users of NPlot to continue its development. If you would like to become part of this effort, please send me an email at mhowlett (at) and I will put you in touch with other interested developers.

30 May 2006 I haven't put much energy into NPlot of late - it has been focused on work and other projects. My original motivation for developing NPlot was to learn C# and .NET. My motivation continued as the opportunity to implement some nice design ideas emerged. Now, the focus is on maintenance and working on the code is not exciting enough to keep me putting in the long hours (for no reward). Please don't let this put you off using NPlot - it's a great way to easily knock up some quick charts and it is used successfully in a number of commercial products. However be aware that I'm not in a position to properly maintain the library, or offer support. I'm still very interested to hear about projects that use NPlot however!
