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.
