Plot Data Extractor

Click plots. Extract values. Fast manual extraction of numerical data and error bars from scientific plots.

Extract numerical data from scientific plots quickly and accurately. Plot Data Extractor is a free Chrome extension for researchers who need numerical values from figures in scientific papers. Calibrate the plot axes, click the data, capture error bars and export the results as CSV. Built for focused manual extraction, it removes much of the setup required by general-purpose plot digitisation software when you already know which points you need. Key features: • XY plots with linear or Log10 axes • Bar charts with categorical groups • X errors, Y errors, both or neither on XY plots • Symmetric, asymmetric or no error bars on bar charts • SD, SE, 95% CI and other/unknown error metadata • One-sided displayed symmetric error-bar capture • Guided CURRENT STEP workflow • High-contrast precision crosshair and open-circle cursor • Action-level Undo and Clear all controls • Source URL provenance in exported data • Timestamped CSV export • PDF captured-view workflow for PDFs displayed in Chrome Local by design Plot Data Extractor accesses only the active tab you choose for extraction. The active page URL may be used as CSV provenance and, for PDFs, the visible tab is captured locally for extraction. Plot images, click coordinates, URLs and extracted data are processed locally in your browser and are not sent to Blazon Scientific or third parties. Plot Data Extractor is intended to assist manual data extraction. Researchers remain responsible for checking extracted values against the source figure and for interpreting error bars and other reported statistics correctly. Developed by Blazon Scientific.
