When expanding a shell variable, the braces aren't needed unless the character following the variable name could be interpreted to be part of the name. So: $current_name/$opt produces exactly the same results as ${current_name}/${opt}, but ${current_name}_abc/${opt}_def is not at all the same as $current_name_abc/$opt_def.

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).
