You specify the pixel size (dx) and its units, and the package automatically renders an appropriately-scaled bar with optional labels, customizable positioning, and support for multiple unit systems (SI length, imperial, astronomical, angle, pixel-based, and reciprocal dimensions).\n\nThe scale bar integrates directly into matplotlib's artist system\u2014you create a ScaleBar object, add it to an axes via add_artist(), and configure appearance through constructor arguments or matplotlibrc settings. It's designed for scientific imaging workflows where pixel dimensions are known and need visual representation on output plots or saved figures.","worth_installing":"Yes. Low install friction, no security issues, permissive license, and recent maintenance make it a safe choice. Install if you regularly plot calibrated images and need a standard way to display scale information; skip if you never use imshow() or prefer manual annotation."},"id":"matplotlib-scalebar","links":{"html":"https://skillfed.io/packages/matplotlib-scalebar","md":"https://skillfed.io/packages/matplotlib-scalebar.md","pypi":"https://pypi.org/project/matplotlib-scalebar/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2025-01-17","license_spdx":null,"license_treatment":"permissive","name":"matplotlib-scalebar","python_support":"supports_current","summary":"Artist for matplotlib to display a scale bar"},"popularity":{"monthly_downloads":148860,"position":11016,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.9.0"}
