Systat Software Announces SigmaPlot Version 13
The most advanced scientific graphing and statistical analysis software, SigmaPlot, now includes Forest and Kernel Density plots, ANCOVA, Principal Components Analysis, new color schemes and significant improvements.
( August 7, 2014 - San Jose, CA -- Systat Software Inc a leading developer and supplier of award-winning scientific software and services today announced SigmaPlot Version 13 their latest version of the most advanced scientific data analysis and graphing software package. This version has multiple new graph features including Forest plots and Kernel Density a smooth probability distribution plot, 10 new color schemes, additional statistics functions for Principal Components Analysis (PCA) and Analysis of Covariance (ANCOVA) and legend improvements which include the Direct Labeling method.

SigmaPlot version 13 provides researchers with an optimized property interface with no tabs, with all properties displayed in one place and instant graph display upon property change. The Graph Properties panel is smaller and has an optional transparency to show graph changes behind it. Version 13 has increased ease of use to quickly analyze data and create exact, publication-quality graphs that best present research results for presentation, publication or the web.

"More than 500,000 scientists and engineers have used SigmaPlot worldwide. It has long been the industry standard for graphing and analyzing data in the scientific and engineering communities because it plays a key role in enabling researchers to visually communicate important research results." said Richard Mitchell, PhD, Senior Scientist at Systat Software, Inc. The new SigmaPlot 13 adds two new analysis methods to extract additional information from your data. Principal Components Analysis finds variables that succinctly describe your data.

Analysis of Covariance (ANCOVA) improves the description of your data by including the effect of "nuisance" variables. A total of 24 probability functions have been added that can be used for function fitting or curve visualization. The Direct Labeling method places the legend items next to their plots rather than in a legend which makes understanding the graph much quicker. Other analysis, user-interface and import/export features together with the simplified Graph Properties dialog introduced in Version 12 combine to make this a significant release", advised Dr. Mitchell.
