The PLPLOT library has been designed so that it is easy to write programs
producing graphical output without having to set up large numbers of
parameters. However, more precise control of the results may be necessary,
and these are accomodated by providing lower-level routines which change
the system defaults. In chapter ![[*]](crossref.png)
, the overall process of
producing
a graph using the high-level routines is described. Chapter
discusses the underlying concepts of the plotting process and introduces
some of the more complex routines. The reference section of the manual,
chapter is an alphabetical list of the user-accessible
PLPLOT functions with detailed descriptions.
