Her problem? A 1983 paper on Iguanodon growth rates contained the only existing isotopic temperature curve for the Cretaceous period. But the data was trapped—a wavy, faint blue line on a scanned, low-resolution graph, complete with coffee stains and hand-drawn axes.

Scientists, engineers, and researchers often find valuable data trapped inside static images. Older research papers, PDF reports, and scanned charts frequently lack the original underlying data tables. Manual reconstruction is tedious and inaccurate.
If a scanned page is slightly tilted, use GetData's built-in axis orientation tools during the scale setup. This corrects any skewing that would otherwise corrupt the X/Y relationship.
Two distinct automated modes trace lines and find data points without requiring manual clicking. Her problem
But the story wasn’t only about technical competence. Digitizing decades-old results felt like time travel. Elena would sit late into the night, leafing through PDFs from the 1980s, breathing life back into plots that hadn’t been touched since they were printed. Each newly extracted dataset was a small rescue mission: a set of numbers returned from oblivion, restored to modern reproducible workflows. She began to appreciate papers in a different way—each figure a compact narrative of an experiment, waiting to be read mathematically.

Once the tracing is finished, review your points in the data window. Click to save your new X,Y coordinates as an Excel spreadsheet or a plain text file for immediate analysis in Python, R, or MATLAB. System Requirements & Technical Specifications
Open the application and load your target image file. If your data is trapped inside a PDF document, take a high-resolution screenshot of the graph first, save it as a PNG or JPEG, and then open it in GetData. Step 2: Calibrate the Axes
For most users, these are minor inconveniences. Follow the on-screen prompts to click four specific
