Dagra

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

Converted data can be used in your analysis

Updates

Released Dagra 1.2.1

A new version of Dagra has been released with improved support for installation under Vista's User Access Control, opening of .dag files from Windows Explorer and clearer node markers on dark backgrounds.

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.
