Dagra provides a simple method to grab data from a graph. Using Bézier curves, you can quickly and accurately digitize numerical data from scanned or graphical images. Add-ins for common analysis tools get you working quickly with the new data. More info...

Printed Data to Numerical Data

Use Dagra to convert printed data into numerical data

Use Dagra to digitize numerical data from printed graphical data for:

  • Design calculations
  • Numerical modelling
  • Simulations
  • Control system development
  • Comparing new results with previous work
Excel, Matlab, Python


Scatter plots now supported

Digitizing scatter plots has been added to Dagra. We've also added support for exporting raw Bezier curves and quickly copying the current mouse position to the clipboard (Ctrl+Shift+C). Dagra has also been updated to use version 3.5 of the Microsoft .NET framework; this is the version that ships with Windows 7.

Python support added to Dagra

A new version of Dagra is released with Python support for opening native Dagra data files (.dag). Default series colours no longer include black to avoid conflict with black traces on graphs.

Subsample exporting added to Dagra
To make it easier use data from Dagra in your analysis we have implemented a new subsampling feature during export. Subsampling lets you specify a range and spacing for the data to export to the clipboard or a text file. Dagra will interpolate your data over the specified range to export only the values you need. Full export of the linearized Bezier curve is still supported.

Dagra video example added
Added a short video clip demonstrating extraction of mean atmospheric carbon dioxide from a screen shot with Dagra.

Dagra Updated

Added screen shot capture, axis matching, series hiding and series shuffling to Dagra.
