We present an application, Superplot, for calculating and plotting statistical quantities relevant to parameter inference from a "chain" of samples drawn from a parameter space, produced by e.g. MultiNest. A simple graphical interface allows one to browse a chain of many variables quickly, and make publication quality plots of, inter alia, profile likelihood, posterior pdf, confidence intervals and credible regions. In this short manual, we document installation and basic usage, and define all statistical quantities and conventions.
