	  ( | p_digmax, | 
| p_digits ); | 
      Identical to plgxax, except that arguments are flags for y axis.
      See the description of plgxax for more detail.
    
p_digmax
	  (PLINT_NC_SCALARReturned value of the maximum number of digits for the y axis. If nonzero, the printed label has been switched to a floating-point representation when the number of digits exceeds this value.
p_digits
	  (PLINT_NC_SCALARReturned value of the actual number of digits for the numeric labels (y axis) from the last plot.
      Redacted form: plgyax(p_digmax, p_digits)
