FindGraph

FindGraph is powerful graph plotting, data-analysis and digitizing tool suitable for students and engineers. With graphics editor you can easily add and move points and draw families of lines. Approximation features like regression analysis, logistic functions and a neural network are included.


FindGraph Main 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.

The program allows you to draw text commentary along any line.

Unlimited Undo/Redo.

You can specify the unlimited number of points and lines. Their graphs will be plotted in one coordinate system, allowing comparison of empirical and analytical data. Lots of graph and coordinate plane parameters.

Supported graph types are:
Scatter diagrams and line graphs;
Points density distributions;
Points groups diagrams.

Zoom is possible.
The graphs allow total freedom in setting up scales and grids. Log scales for each axis are available. Points color, size and aspect ratio are taken into account under approximation line build.

Approximation features like regression analysis, logistic functions and a neural network are included.

Regression curve fits are 1st to 5th order polynomial, power, exponential, or log.

Ability to build parametric line graphs X(u,v), Y(u,v). The program allows you to draw families of lines with a given step of parameter. Bessel, Beta, Gamma, Normal and other math functions.

FindGraph allows you to export information to the other programs and files. Points can be saved to ASCII tables. Regressiion lines, curves, points and commentaries can be saved to XML file.

FindGraph is COM server. This means, that plot can be copied and pasted (embedded) directly into word processors, Excel or drawing programs.

High-quality graphs are optimized for printing. The program has preview capabilities.

The program supports OLE automation and can be built-in to user software.

Examples (MS VB, MS VC++) are included. Methods and properties are documented.
