Extract raw data from dead pixels.
Don't guess the values on that flattened PDF report. Graphshot reconstructs the original datasets from screenshots of scatter plots, bar charts, and logarithmic graphs.
The Toolkit
Scatter Digitiser
Extract X,Y coordinate pairs from dense scatter plots. Handles overlapping points and distinct marker shapes.
Log Scale Resolver
Accurately calculate values on logarithmic or semi-log axes where linear pixel interpolation fails.
Error Bar Reader
Measure standard deviation and confidence intervals directly from graphical error bounds.
Why standard OCR fails on charts
Optical Character Recognition (OCR) is built for text. When applied to a chart, it might read the axis labels, but it cannot understand the spatial relationship between a plotted point and those labels. The pixel distance must be mathematically mapped to the coordinate space.
"In our 2023 analysis of 500 published medical papers, over 60% of datasets were only available as flattened charts. Re-extraction requires pixel-perfect geometric mapping, not just text reading."
Graphshot handles the geometry. You define the axes by clicking known reference points, and our algorithms construct a transformation matrix to convert any subsequent pixel click into accurate data values.
