matplotlib/matplotlib has 256,762 source lines of code out of 332,379 total lines across 1,232 files, counted from the cfa473e42fa41572d9acbd8d6b7be6f1489dee46 ref at commit cfa473e42fa4 by the OctoCounts tokei engine on 2026-09-17. The report is cached by commit, tokei version, and analysis options, so recounting the same revision returns exactly these numbers.

OctoCounts produced this report by resolving matplotlib/matplotlib to commit cfa473e42fa4, downloading the repository source archive, and counting every source file with tokei, the open-source line counter written in Rust. The table below breaks the count down by programming language into files, total lines, code lines, comment lines, and blank lines, so the figures can be compared across languages and projects. Results are cached by commit, tokei version, and analysis options, so counting the same revision again reproduces exactly these numbers.
