A web based tool to extract numerical data from plot images. Supports XY, Polar, Ternary diagrams and Maps.

This tool has been developed using HTML5, CSS3 and Javascript and therefore runs from within the browser and requires no installation.

This project is hosted on http://arohatgi.info/WebPlotDigitizer.

Instructions and video tutorials are available at http://arohatgi.info/WebPlotDigitizer/?page_id=58.

This tool has to hosted on a HTTP server for some javascript features to function correctly. Therefore, host this on a server (ex: Apache) while developing or using offline.
