Major Versions

ScottPlot 4.0 is stable, available on NuGet, and has its own branch for continued bug fixes and refinements. However, new features are no longer being developed for this version.

Plot in the Cloud

This figure is an example of ScottPlot running in the cloud. Once daily an Azure Function logs the number of stars this repository has and creates a graph of the star history using ScottPlot. Since the output is simply a static image accessible by a URL, it can be displayed in places where JavaScript is not permitted like in this readme file. Rendering plots server-side allows automatically-updating plots to be displayed in many interesting places. Source code can be found in the StarGraph repository.

Developer Notes

Minimum Supported Platforms: .NET Core 2.0 and .NET Framework 4.6.1 (see details)
The ScottPlot Roadmap summarizes ScottPlot's origins and tracks development goals. If there is a pinned Triaged Tasks and Features issue on the issues page, it likely indicates what I am currently working on.
