SigmaPlot

SigmaPlot is a proprietary software package for scientific graphing and data analysis. It runs on Microsoft Windows.

The software can read multiple formats, such as Microsoft Excel spreadsheets, and can also perform mathematical transforms and statistical analyses. A single, perpetual product license costs between $700 and $1300 depending on academic, corporate, or government affiliation. This perpetual license cost may be inaccurate as Grafiti LLC requires a discussion of quote to receive a license now.

A free 30-day trial used to be available, however, since development was taken over by Grafiti LLC, this trial is no longer offered.
