Open Source C# Charting Libraries

LiveCharts2 is a flexible data visualization library for .NET applications that need interactive charts, maps, and gauges. It is designed as the evolution of the original LiveCharts project, with a new architecture focused on running across many UI frameworks. Developers can use one API across targets such as MAUI, WPF, WinUI, Windows Forms, Blazor WebAssembly, Avalonia, Uno Platform, UWP, Xamarin.Forms, and Eto Forms. The library supports common data visualization patterns through Cartesian, polar, pie, gauge, and map views. It can handle multiple series types, configurable axes, tooltips, legends, zooming, and panning. It is a strong fit for dashboards, analytics tools, monitoring screens, and business apps that need attractive live visual feedback without rewriting chart logic for each platform.

NPlot is an open source charting library for .NET. It boasts an elegant and flexible API. NPlot includes controls for Windows.Forms, ASP.NET and a class for creating Bitmaps. A GTK# control is also available.

Microcharts is an extremely simple charting library for a wide range of platforms (see Compatibility section below), with shared code and rendering for all of them! This project is just simple drawing on top of the awesome SkiaSharp library. The purpose is not to have an heavily customizable charting library. If you want so, simply fork the code, since all of this is fairly simple. Their is no interaction, nor animation at the moment.

Satsuma is a graph library for .NET, written in C#. Satsuma is an easy-to-use and flexible library, which implements all the necessary graph structures, and the fastest possible graph algorithms. DOCUMENTATION: http://satsumagraph.sourceforge.net/ Satsuma is not a charting library. 'Graph' is used in the mathematical sense here (e.g. nodes connected with arcs). Satsuma is released under the zlib license. This license is very permissive and allows you to use Satsuma for both personal and commercial purposes.

A plotting (chart) library for .NET. Provides the ability to create plots with a minimum of effort and also to customise them extensively where required.
