  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, one- and two-dimensional profile
likelihood, posterior pdf (with kernel density estimation), confidence
intervals and credible regions. In this short manual, we document installation
and basic usage, and define all statistical quantities and conventions. The
code is fully compatible with Linux, Windows and Mac OSX. Furthermore, if
preferred, all functionality is available through the command line rather than
a graphical interface.
