Winplot is a general-purpose plotting utility for Microsoft Windows that can draw (and animate) curves and surfaces presented in a variety of formats.[4]

As of 2015, Winplot can run on Windows 95, 98, Me, 2000, XP, Vista, 7, and likely 8 and 10. It is released as freeware, with no source code available.[4]

The author of Winplot, Rick Parris, died on October 23, 2012. He was 67.[5]

Winplot can generate both 2D and 3D plots of functions and sequences. It can also animate these plots using up to 23 variables and their corresponding sliders. As of 2012, only one slider may be animated at a time. It also has various export options including EPS, SVG, PiCTeX, Metafile, and simple copying to the Windows clipboard.

A notable strength is Winplot's ability to plot graphs that are typically unavailable on other (especially free) plotting software, such as implicit functions, slope fields, and intrinsic curves (curvature defined by arclength). Also, several standard calculus operations can be performed on the functions, including generating graphs of cross-sectional solids and solids of revolution, tracing trajectories on slope fields given an initial point, and calculating line and surface integrals.
