NAME

       plstransform - Set a global coordinate transform function

SYNOPSIS

       plstransform(coordinate_transform, coordinate_transform_data)

DESCRIPTION

       This function can be used to define a coordinate transformation which affects all elements
       drawn within the current plot  window.   The  coordinate_transform  callback  function  is
       similar  to  that provided for the plmap(3plplot) and plmeridians(3plplot) functions.  The
       coordinate_transform_data   parameter   may   be   used   to   pass    extra    data    to
       coordinate_transform.

       Redacted form: General: plstransform(coordinate_transform, coordinate_transform_data)

       This function is used in examples 19 and 22.

ARGUMENTS

       coordinate_transform (PLTRANSFORM_callback(3plplot), input)
              A  callback  function  that  defines the transformation from the input (x, y) world
              coordinates to new  PLplot  world  coordinates.   If  coordinate_transform  is  not
              supplied (e.g., is set to NULL in the C case), then no transform is applied.

       coordinate_transform_data (PLPointer(3plplot), input)
              Optional extra data for coordinate_transform.
