The value associated with the i'th bin is placed in \fIx\fP[i], and the number of points in the bin is placed in \fIy\fP[i]. For proper operation, the values in \fIx\fP[i] must form a strictly increasing sequence. By default, \fIx\fP[i] is the left-hand edge of the i'th bin. If \fIopt\fP=PL_BIN_CENTRED is used, the bin boundaries are placed midway between the values in the \fIx\fP array. Also see \fBplhist\fP(3plplot) for drawing histograms from unbinned data. .P Redacted form: General: \fBplbin(x, y, opt)\fP Perl/PDL: \fBplbin(nbin, x, y, opt)\fP Python: \fBplbin(nbin, x, y, opt)\fP .P This function is not used in any examples. .SH ARGUMENTS .TP \fInbin\fP (PLINT, input) Number of bins (i.e., number of values in \fIx\fP and \fIy\fP arrays.) .TP \fIx\fP (const PLFLT *, input) Pointer to array containing values associated with bins. These must form a strictly increasing sequence. .TP \fIy\fP (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. .TP \fIopt\fP (PLINT, input) Is a combination of several flags: \fIopt\fP=PL_BIN_DEFAULT: The \fIx\fP 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. \fIopt\fP=PL_BIN_CENTRED|...: The bin boundaries are to be midway between the \fIx\fP values. If the values in \fIx\fP are equally spaced, the values are the center values of the bins. \fIopt\fP=PL_BIN_NOEXPAND|...: The outer bins are drawn with equal size as the ones inside. \fIopt\fP=PL_BIN_NOEMPTY|...: Bins with zero height are not drawn (there is a gap for such bins). .SH AUTHORS Many developers (who are credited at http://plplot.sourceforge.net/credits.php) have contributed to PLplot over its long history. .SH SEE ALSO PLplot documentation at http://plplot.sourceforge.net/documentation.php.
