Get x axis parameters
plgxax(p_digmax, p_digits)
Returns current values of the p_digmax and p_digits flags for the x axis. p_digits is updated after the plot is drawn, so this routine should only be called after the call to plbox(3plplot) (or plbox3(3plplot)) is complete. See the PLplot documentation for more information.
Redacted form: plgxax(p_digmax, p_digits)
This function is used in example 31.
p_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 p_digmax.
p_digits (PLINT *, output)
Pointer to variable with the actual number of digits for the numeric labels (x axis) from the last plot.
