[update: the beta testing is currently underway]

Beta program

The beta program for GraphExpert Pro is set to open in the last week of January, and will likely last for 4-6 weeks.  Any beta participant will receive a free copy of GraphExpert Professional for helping.  We are in need of approximately 30 testers; if you are interested in joining the beta program, please send an email to dhyams@gmail.com with the word "BETA" in the subject line. Note that it doesn't take much to be a beta tester; while heavy exercise of all of the features is appreciated greatly, just using it in the course of your daily work and reporting any problems that you run into is certainly sufficient.

GraphExpert Professional is a brand new data manipulation and graphing application.  It is intended to work with raw data from your files, perform transformation, manipulations, and analysis on that data, and finally visualize the resulting datasets and/or functions using a publication quality graphing engine.  There are facilities for direct function creation as well.  The entire system is pipeline-based, so that any changes in your data are automatically reflected in any derived datasets from that data, as well as the visualization is automatically updated. A quick couple of samples of GraphExpert Professional as it exists at this moment is shown below:

We are very excited about the potential of GraphExpert Professional, and hope that you will participate in the beta!  GraphExpert Professional has been under construction for over a year; participants at the CurveExpert Forums will recall an RFC (request for comment) release in May of 2012.

 What is the difference between CurveExpert Pro and GraphExpert Pro?

CurveExpert Pro is meant primarily for nonlinear regression analysis (curve fitting), and is designed around an approach that requires one dataset at a time.

GraphExpert Pro, on the other hand, is capable of managing and analyzing multiple datasets at one time (as well as datasets derived from those datasets).  The operations that one can perform on datasets are more varied than CurveExpert (transformations, linear regressions, histograms, FFT, etc.), but at the same time, the heavy-duty curve fitting capability in CurveExpert Pro is not included.  For example, one cannot create a custom nonlinear regression model and compute its best fit to the data.

 

Interoperability

GraphExpert Pro is capable of receiving computed results from CurveExpert Pro and graphing them.  Also, the dataset from CurveExpert Pro can easily be cut and pasted in to a GraphExpert Pro document.
