man plbin () - Plot a histogram from binned data
NAME
plbin - Plot a histogram from binned data
SYNOPSIS
plbin(nbin, x, y, center)
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. If center=0, x[i] is the left-hand edge of the i'th bin, and if center=1, the bin boundaries are placed midway between the values in the x array. Also see plhist(3plplot) for drawing histograms from unbinned data.
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 probabilities, etc.
- center (PLINT, input)
- Indicates whether the values in x represent the lower bin boundaries (center=0) or whether the bin boundaries are to be midway between the x values (center=1). If the values in x are equally spaced and center=1, the values in x are the center values of the bins.
