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 (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).
