You wish to compare and display the data obtained from independent sources. Typically input data sources are graphs 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 graphs, regression line or approximations displayed with commentaries that can be exported into a document by using cut and paste.

Use FindGraph . Powerful but easy-to-use data-analysis, digitizing, graph plotting program.

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.

It is possible to add points interactively. The program has a full set of drawing tools. You can easily:

- Add, move, copy and delete single points and series of points;
- Add and move areas;
- Remove and duplicate graphs (approximation lines);
- Add and move text commentary. Possible draw text commentary along any line.

Unlimited Undo/Redo. You can specify an unlimited number of points, areas and lines. Their graphs will be plotted in one coordinate system, allowing comparison of empirical and analytical data. Choose from many graph and coordinate plane parameters. It is possible to quickly hide/show series of points and graphs. Visualization features:

- Scatter diagrams and lines;
- 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. Point's color, size and aspect ratio are taken into account under approximation line build. Some of the data-analysis features are:

- Regression analysis and correlation factors;
- Regression curve fits are 1st to 20th order polynomial, power, exponential, or log;
- Logistic functions;
- Fourier approximation;
- Neural network is used for approximation;
- Splines;
- Irregular dependencies search.

You can use your own algorithm as Plug-In.

There is ability to build parametric graphs X(u,v), Y(u,v). Families of lines with a given step of parameter v can be plotted.

The program allows you to export information to the other programs and files. Points can be saved to ASCII tables. Approximation lines, areas, 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. To edit embedded plot, double click the mouse button on it.

Graphs are optimized for printing. The program has preview capabilities.

The program supports OLE automation and can be built-in in user software. Some commented samples (VB, C++) are included.
