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.

CurveExpert Professional v1.6.5 x86

with fixed medicine from Jule, 20 

CurveExpert Professional is a cross-platform solution for curve fitting and data analysis. Data can be modelled using a toolbox of linear regression models, nonlinear regression models, smoothing methods, or various kinds of splines.

Over 90 models are built-in, but custom regression models may also be defined by the user. Full-featured publication-quality graphing capability allows thorough examination of the curve fit. The process of finding the best fit can be automated by letting CurveExpert compare your data to each model to choose the best curve. The software is designed with the purpose of generating high quality results and output while saving your time in the process.

CurveExpert Professional compares very favorably to the competition and does so at a lower price; see the interactive comparison for more information.
