n (PLINT(3plplot), input)
Number of data points.
data (PLFLT_VECTOR(3plplot), input)
A vector containing the values of the n data points.
datmin (PLFLT(3plplot), input)
Left-hand edge of lowest-valued bin.
datmax (PLFLT(3plplot), input)
Right-hand edge of highest-valued bin.
nbin (PLINT(3plplot), input)
Number of (equal-sized) bins into which to divide the interval xmin to xmax.
opt (PLINT(3plplot), input)
Is a combination of several flags: opt=PL_HIST_DEFAULT: The axes are automatically rescaled to fit
the histogram data, the outer bins are expanded to fill up the entire x-axis, data outside the
given extremes are assigned to the outer bins and bins of zero height are simply drawn.
opt=PL_HIST_NOSCALING|...: The existing axes are not rescaled to fit the histogram data, without
this flag, plenv(3plplot) is called to set the world coordinates.
opt=PL_HIST_IGNORE_OUTLIERS|...: Data outside the given extremes are not taken into account. This
option should probably be combined with opt=PL_HIST_NOEXPAND|..., so as to properly present the
data. opt=PL_HIST_NOEXPAND|...: The outer bins are drawn with equal size as the ones inside.
opt=PL_HIST_NOEMPTY|...: Bins with zero height are not drawn (there is a gap for such bins).
