Researchers and data scientists frequently encounter valuable data locked inside static formats like journal articles, old textbooks, or unexportable vector graphics. Manually guessing coordinate points is highly inaccurate and time-consuming. Graph digitizers solve this by allowing you to:

Prepare the image
is a software tool designed to extract numerical data from raster images of graphs (e.g., scanned scientific plots, charts, diagrams). It is widely used in research and engineering when raw data is unavailable. However, a critical fact must be stated immediately:

Supports XY plots, bar charts, polar plots, ternary diagrams, and maps.
Yes – both Engauge and WebPlotDigitizer handle log axes natively.
Extracting precise data points from scanned graphs, PDFs, and images is a critical task for researchers, engineers, and students. For years, has been a go-to Windows application for converting graph images into usable numerical data.
Two points on the (e.g., the minimum and maximum scale values).
