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 $899 and $1599 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.

As of version 16, a free 30-day trial is available via the website.
