plbin: Plot a histogram from binned data 

DESCRIPTION:

    This function is not used in any examples. 

SYNOPSIS:

plbin(nbin, x, y, opt)

ARGUMENTS:

    nbin (PLINT, input) :    Number of bins (i.e., number of values in x
    and y arrays.) 

    x (const PLFLT *, input) :      Pointer to array containing values
    associated with bins.  These must form a strictly increasing
    sequence. 

    y (const PLFLT *, input) :      Pointer to array containing number of
    points in bin.    This is a PLFLT (instead of PLINT) array so as to
    allow histograms of probabilities, etc. 

    opt (PLINT, input) :    Is a combination of several flags:
    opt=PL_BIN_DEFAULT: The x represent the lower bin boundaries, the
    outer bins are expanded to fill up the entire x-axis and bins of
    zero height are simply drawn. 
        opt=PL_BIN_CENTRED|...: The bin boundaries are to be midway
        between the x values. If the values in x are equally spaced,
        the values are the center values of the bins. 
        opt=PL_BIN_NOEXPAND|...: The outer bins are drawn with equal
        size as the ones inside. 
        opt=PL_BIN_NOEMPTY|...: Bins with zero height are not drawn
        (there is a gap for such bins).
