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.
