Powerful data analysis tool. Digitizing and graph plotting software suitable for students, engineers, scientists and those who work with 2D line graphs. Calculate regression lines and neural network approximations quickly with ease.
The problem.
You wish to compare and display the data obtained from independent sources. Typically input data sources are line graphs or scatter diagrams from Internet pages, text files, Excel tables or personal raw data. You want the ability to remove false points and add desirable points interactively.

Desired outcome - mated line graphs, regression line or approximations displayed with commentaries which can exported into a document by using cut and paste.

The features.

Graphs can be generated:
From character-delimited text files using an Excel-like data import feature;
From the contents of the Clipboard table data (Excel spreadsheets);
From digitizing screen charts;
From the text editor.

With graphical editor you can easily:
Add, move, copy and delete single points or a series of points;
Remove and duplicate graphs or approximation lines;
Add and move text commentary.
It is possible to draw text commentary along any line.
