GraphExpert Professional v1.1 x86 

GraphExpert Pro is a cross-platform solution for publication-quality graphing of both discrete data and continuous functions. XY plots, bar charts, polar plots, scatterplots, contour plots, and 3D scatter/surface plots are supported (see the gallery). Also, graphs can be annotated with a variety of drawing tools such that annotations, arrows, and images can quickly and easily be added to the plot.

GraphExpert Pro takes a unique approach in managing the multiple datasets and functions. Datasets may be derived from other datasets in a multitude of ways (extraction, transformations, histogramming, etc.), and a parent/child relationship is always maintained. This means that you can concentrate on the required operations to process your raw data into a usable form, and if the raw data changes for any reason, all of the operations update automatically. Further, any datasets that are already on a graph update automatically. This means less time performing repetitive work, and more time for the real task at hand.

As a simple example for illustration, imagine that you have a raw dataset in a file, and you would like to plot columns 1 and 3 of the dataset along with a best-fit line. Simply import the raw dataset into GraphExpert Pro, extract the first and third columns, and then run a linear regression on that extraction. Then drag and drop both the extraction and linear regression onto a plot for visualization. GraphExpert Pro keeps track of the operations that you performed, so that if the raw dataset is modified in any way, the extraction, linear regression, and the plot is updated automatically. The procedure is intuitive and easy.

Data analyses such as regression, creation of histogram data, ANOVAs, t-tests, computing integrals/differences, moving averages, processing replicates, and computing Fast Fourier Transforms are supported.
