WebPlotDigitizer
Opensource computer vision assisted software to help extract numerical data from images of plots, maps and much more.
Features
A large quantity of useful data is hidden behind data visualizations that are only shared as images. WebPlotDigitizer makes it easy to extract this information using a mix of computer vision algorithms and manual tools.
- Work with a wide variety of charts: XY (line and scatter), Bar Charts, Histograms, Polar, Ternary and even Circular Chart Recorders.
- Load multiple files at once including PDF documents. Work with any image format that's supported by your browser.
- Make simple measurements like distance, angles, area and perimeter.
- Privacy focused: All algorithms are implemented in client side Javascript and images/documents are never uploaded to a remote server. 100% Offline version is also available for download.
- Translated to Simplified Chinese, German and French.
