plgxax: Get x axis parameters 

DESCRIPTION:

	Returns current values of the digmax and digits flags for the x axis. 
	digits is updated after the plot is drawn, so this routine should only
	be called after the call to plbox (or plbox3) is complete.	See the
	PLplot documentation for more information. 

SYNOPSIS:

plgxax(digmax, digits)

ARGUMENTS:

    digmax (PLINT *, output) :      Pointer to variable with the maximum
        number of digits for the x axis.  If nonzero, the printed label
        has been switched to a floating point representation when the
        number of digits exceeds digmax. 

    digits (PLINT *, output) :      Pointer to variable with the actual
        number of digits for the numeric labels (x axis) from the last
        plot.
