Click the point on your graph and input its real numerical value. Click the X-max point and input its value. Repeat this process for Y-min . Repeat this process for Y-max .
Which do you plan to export the data into? (e.g., Excel, Python, MATLAB)
: Two distinct algorithms automatically trace lines or digitize entire areas. getdata graph digitizer 2.24
: Open a graph image in formats like TIFF, JPEG, BMP, or PCX. : Set the scale by defining the X and Y coordinate systems.
Before the software can calculate data points, it needs to understand the scale of your graph. You must calibrate the axes: Click the or axis calibration tool. Select two points on the X-axis ( X1cap X sub 1 X2cap X sub 2 ) and enter their real numerical values. Select two points on the Y-axis ( Y1cap Y sub 1 Y2cap Y sub 2 ) and enter their real numerical values. Specify whether your axes are Linear or Logarithmic . Step 3: Digitize the Points Click the point on your graph and input
Automated tracing saves hours of manual data entry.
For most users, these are minor inconveniences. Repeat this process for Y-max
Version 2.24 refines the core digitizing algorithms to improve accuracy and speed up workflows.
In the world of scientific research, engineering, and data analysis, we often encounter a frustrating paradox: the data we need exists, but not in a usable format. It is trapped within static images—scanned journal pages, screenshots of old presentations, or archived PDFs with broken data links.
With a clean image and careful clicking, you can achieve errors under 1% of the axis range. For example, on a 0-100 axis, typical error is 0.5–1 units.
