We describe simple use of PLplot in this chapter which includes many cross-references to elements of our common (C) API that use PLplot C types such as PLFLT and PLINT. For full documentation of all PLplot C types see here. The best way to learn how to use our common API for the language of your choice is to look at our standard set of examples. For additional language documentation you should consult the various chapters in Part III, “ Supported computer languages ” as well.
