This common API between the various languages constitutes the most important part of the PLplot API that programmers need to know. Note that in C, these common API routines have a special "c_" prefix name assigned to them in plplot.h.
What follows is a list of all common API functions of the current CVS HEAD with their arguments except for obsolete/deprecated API functions which are listed in Chapter 24. The following information is provided for each function:
The function name and a brief description.
The function as it would be called from C.
A complete description of the function.
A description of each argument that the function takes.
The redacted argument form of the function, currently used by the programming languages Fortran95, Python, Java and Perl, as well as any language specific variations that might occur on the general calling scheme described in the following paragraph.
A list of PLplot examples that demonstrate how to use the function.
The general calling scheme for the other languages supported
by PLplot is as follows, using the function
plline as an example.
C: plline(n,x,y)
F77: plline(n,x,y)
F95: plline(x,y)
C++: pls->line(n,x,y)
Java: pls.line(x,y)
Perl/PDL: plline($x,$y)
Python: plline(x,y)
Tcl/Tk: $w cmd plline $n x y
pl_setcontlabelformat: Set
format of numerical label for contours
Set format of numerical label for contours.
