NAME

6       plstransform - Set a global coordinate transform function

SYNOPSIS

9       plstransform(transform_fun, data)
10

DESCRIPTION

12       This  function  can be used to define a coordinate transformation which
13       affects all elements drawn within the current plot window.  The  trans‐
14       formation  function  is similar to that provided for the plmap(3plplot)
15       and plmeridians(3plplot) functions.  The data parameter may be used  to
16       pass extra data to transform_fun.

18       Redacted form:  General: plstransform(transform_fun, data)

ARGUMENTS

24       transform_fun  (void  (*)  (PLFLT,  PLFLT, PLFLT*, PLFLT*, PLPointer) ,
25       input)
26              Pointer to a function that defines  a  transformation  from  the
27              input (x, y) coordinate to a new plot world coordiante.
28
29       data (PLPointer, input)
30              Optional extra data for transform_fun.
