plbin(nbin, x, y, cen)

  plbin

[] Plots a histogram consisting of n 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. If center is false, x[i] is the left-hand edge of the i'th bin, and if center is true, the bin boundaries are placed midway between the values in the x array. Also see plhist for drawing histograms from unbinned data.

[] 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 probabilities, etc.

[] cen (PLINT, input):[]Indicates whether the values in x represent the lower bin boundaries (cen=0) or whether the bin boundaries are to be midway between the x values (cen=1). If the values in x are equally spaced and cen=1, the values in x are the center values of the bins.
