Find Graph Quick and Easy

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 nonlinear regression or curve fitting. Then print your results or export them to Excel or other database.

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 (finance.yahoo.com).

You can see chart and digitized data points. Then we build approximation line and apply SSA and GMDH or RNN to reconstruct and to forecast data series. The best way you can learn about FindGraph is to download and try out the 30-day evaluation version.
