Data Digitiziar

A self-contained browser digitizer for plot images. Upload a figure, define the plot area, calibrate the axes, and extract points or color-matched curves entirely in the browser.

Image workspace

Upload a plot image, then drag to define the plot box. Click inside the box to add manual points, then place one seed point on the target curve before running auto extraction.

Ready Upload an image to begin.

Axis calibration

The plot box can be set manually on the canvas. Add an orange legend exclusion box when the legend overlaps the plot. The axis inputs turn pixel positions into physical coordinates for export.

Results

No points yet. Manual clicks and auto extraction will appear here.
