plbin

PLBIN(3plplot)							    PLplot API							    PLBIN(3plplot)

NAME

       plbin - Plot a histogram from binned data

SYNOPSIS

       plbin(nbin, x, y, opt)

DESCRIPTION

       Plots  a  histogram consisting of nbin bins.  The value associated with the i'th bin is placed in x[i], and the number of points in the bin
       is placed in y[i].  For proper operation, the values in x[i] must form a strictly increasing sequence.  By default, x[i] is  the  left-hand
       edge  of  the  i'th  bin.  If opt=PL_BIN_CENTRED is used, the bin boundaries are placed midway between the values in the x array.  Also see
       plhist(3plplot) for drawing histograms from unbinned data.

       Redacted form:  General: plbin(x, y, opt) Perl/PDL: plbin(nbin, x, y, opt) Python: plbin(nbin, x, y, opt)

       This function is not used in any examples.

ARGUMENTS

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

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

       y (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  proba-
	      bilities, 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).
