PLplot has historically had C and Fortran language bindings. PLplot version 5.0 introduces a plethora of new programming options including C++ (described earlier) and several script language bindings. The Tcl interface to PLplot (which the PLplot maintainers regard as the “primary” script language binding) is described in this chapter, with further discussion of Tcl related issues following in additional chapters. But Tcl is certainly not the only script language option. Bindings to Perl, Python, and Scheme (which is actually another compiled language, but still has some of the flavor of a VHLL) are in various stages of completion, and are described in separate chapters. Use the one that suits you best--or try them all!
