NuPlot is a plotting library for WPF aiming to be for WPF what NPlot was for Windows Forms. That is, a no-frills, fast and simple plotting library focusing on the data and not on the prettiness -- the "chartjunk" in Edward Tufte's words.
That said, the project in its current state certainly has some way left to reach the goal. It's not mature yet, but it can be useful nevertheless.

Make sure that axes with decreasing/non-increasing ranges are handled properly. Automated builds. Auto-assign line/marker colors for plots with multiple series (optionally). Handle cultures properly.
Support Silverlight in addition to WPF. Data binding: additional tests. XmlDocs/IntelliSense. Point plot: support a variety of marker shapes. Expose fonts etc as dependency properties. Add a line plot to the sinc demo, like NPlot. Design description. Developers' manual. LinearAxis.ChooseLargeTickStep - ugly code with TODO needs testing & refactoring Step plot: "Center" flag, like NPlot. Improve DataContext forwarding on the PlotCollection? LinearAxis: converter object (as parameter) which can convert from e.g. TimeSpan to double
