AST_GRFPOP - Restore previously saved graphics functions used by a Plot

Description:
The AST_GRFPUSH and AST_GRFPOP functions are intended for situations where it is necessary to make temporary changes to the graphics functions used by the Plot. The current functions should first be saved by calling AST_GRFPUSH. New functions should then be registered using AST_GRFSET. The required graphics should then be produced. Finally, AST_GRFPOP should be called to restore the original graphics functions.
Invocation:
CALL AST_GRFPOP( THIS STATUS )
Arguments:
THIS = INTEGER (Given)
Pointer to the Plot.
STATUS = INTEGER (Given and Returned)
The global status.
Notes:
  • This routine returns without action if there are no snapshots to restore. No error is reported in this case.
