PLplot has long had C and Fortran bindings, presenting a fairly conventional API to the applications programmer. Recently (1994 onwards) PLplot has been growing interfaces (language bindings) to a variety of other languages. In this chapter we discuss the PLplot C++ support provided in the PLplot distribution. Of course many other approaches are possible, perhaps even in use by PLplot users around the world. The purpose of this chapter then is to explain the rationale and intended usage for the bundled C++ language support.
