Are you an engineer, scientist or graduate student looking for a graphing tool that will allow you to quickly analyze graphed data without having to immerse yourself into calculus and statistics books?

The problem
Sometimes it is necessary to compare the data obtained from independent sources to modern data. 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.

The solution
Use FindGraph. It's quick and easy! FindGraph is a comprehensive, feature-rich graphing, digitizing and curve fitting software specially created for these purposes. Take any graph or data from any source (Web or PDF document, for example) add your comments and perform any manipulations, like building approximation lines. Then print your results or export them to Excel or other database.

If your goal is simply to create a smooth curve for interpolation or simulation, FindGraph is the tool you need.

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

This is a data analysis sample. We have digitized points from stocks chart (Yahoo.com). You see points density distribution. Then we build three approximation lines. Click on picture to enlarge.

FindGraph is an engineering and science tool that simplifies the task of curve fitting and regression analysis. What sets FindGraph apart from similar curve fitting and regression programs is its ease of use.
FindGraph supplies 10 generic fits, including Linear Regression, Logistic Functions, Fourier approximation, Neural Networks plus a library of over 120 industry-specific formulas.

The Wizard of Approximation will help you to apply a variety of curve fits to your plot to discover the best model to describe your data. With FindGraph, even a statistical novice can find the best equation in just a few minutes.

Utilize one of predefined curve fits or enter your own equation to fit your data.

All fits are calculated with incredible speed and accuracy. You can fit data to lines or curves. Regression curve fits are 1st to 5th order polynomial, power, exponential, or log.

The program uses several non-linear least-square curve fitting algorithms. The simplex and gradient algorithms were used for quick nonlinear regression performance. You can input desirable formula (analytical function) and vary the number of parameters.

Neural network approximation is equally suited for advanced and inexperienced users. You can use your own curve fitting algorithms as plug-ins. We shipped samples (pure C).
