Core Plot (macOS)
Cocoa plotting framework for macOS, iOS, and tvOS
Core Plot is a 2D Cocoa plotting framework for macOS, iOS, and tvOS. It is highly customizable and capable of drawing many types of plots. See the Example Graphs wiki page and the example applications for examples of some of its capabilities.
Documentation of the Core Plot API and high-level architecture can be found in the following places:
Core Plot is an open source project hosted on GitHub. There are two code repositories under the main project:
Everyone has a their own preferred coding style, and no one way can be considered right. Nonetheless, in a project like Core Plot, with many developers contributing, it is worthwhile defining a set of basic coding standards to prevent a mishmash of different styles which can become frustrating when navigating the code base. See the file CONTRIBUTING.md found in the .github directory of the project source for specific guidelines.
Because Core Plot is intended to be used in scientific, financial, and other domains where correctness is paramount, unit testing is integrated into the framework. Good test coverage protects developers from introducing accidental regressions and frees them to experiment and refactor without fear of breaking things. See the unit testing wiki page for instructions on how to build unit tests for any new code you add to the project.
