Comparison of HP graphing calculators

A graphing calculator is a class of hand-held calculator that is capable of plotting graphs and solving complex functions. While there are several companies that manufacture models of graphing calculators, Hewlett-Packard is a major manufacturer.

The following table compares general and technical information for a selection of common and uncommon Hewlett-Packard graphing calculators. See the individual calculators' articles for further information.
