OxyPlot

OxyPlot is a .NET library that can be seamlessly embedded on any application relying on the two-dimensional coordinate systems. The idea behind the library is to provide a simplistic solution that can be applied on multiple platforms without having to re-write the code.

The library is designed on the standard X and Y coordinate system and hence, supports typical plots such as vertical and horizontal axes, pie charts, polar and Cartesian. There are multiple axes supported and it is even possible to extend functionality with custom types. At the same time, annotations and series can be added to the same plots, which can also be extended.

The library supports customization and it should be fairly easy to change the visuals on the plots by editing the properties. According to the developers, plots can be customized even more by deriving sub classes and hence, taking control of rendering and behavior.

It is important to note that there are some limitations to the library, the first ones being that animations, gradients and hatch brushes are not supported. The controls behind the plot are unable to detect changes in collections and properties so developers need to manually refresh the plots when changing the data.
