GraphExpert Professional 1.3

GraphExpert Professional 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), 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. 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.
What's new in this version:
NEW: Added the ability digitize datasets from a source image. The digitized data becomes a component in GraphExpert Pro. RESOLVED: when drawing a line on a log plot, the points were not evenly spaced in log scale. Fixed. RESOLVED: transparency setting was lost from a contour once the graph properties dialog was exited. Fixed. RESOLVED: import of noisy_sin.dat, which had special tags at the top of the file, gave these special lines as the column headers. Fi...
