WebPlotDigitizer

Overview of WebPlotDigitizer

WebPlotDigitizer is a powerful computer vision-assisted software that extracts numerical data from images of data visualizations. A significant amount of valuable research data remains locked within chart images, making accurate data extraction challenging. This web-based tool combines multimodal machine learning methods with traditional computer vision algorithms to reverse engineer chart data with precision, serving researchers, academics, and data analysts across various scientific disciplines.

Since its creation nearly 14 years ago, WebPlotDigitizer has been cited in thousands of studies and even referenced in XKCD comics, demonstrating its widespread adoption in the research community. Built using HTML5 technology, it runs entirely within your browser without requiring installation, making it accessible across different operating systems. The tool is listed under eLearning CMS and Classroom Tools categories on ToolPicker.

How to Use WebPlotDigitizer

Using WebPlotDigitizer is straightforward: simply upload your chart image or PDF document through the web interface, select the appropriate chart type from the supported formats, and use the AI-assisted tools to define axis points and data series. The computer vision algorithms will semi-automate the digitization process, allowing you to manually refine the extracted data points as needed. The entire workflow happens within your browser, eliminating the need for software downloads or complex installations.
