**12.3****
****Value Operations of Histograms** (.NET, C#, CSharp, VB, Visual Basic, F#)

The **Histogram**
class has the following read-only properties:

● Bins gets the bin boundaries as an array of **Interval** objects.

● Counts gets the counts for each bin as an array of integers.

● NumBins gets the number of bins in the histogram.

● NumSmaller gets the number of data points that were smaller than the smallest bin boundary.

● NumLarger gets the number of data points that were larger than the largest bin boundary.

● Total gets the total number of data points added to the histogram.

Similarly, the Count() member function gets the bin count for a given bin. Reset() resets all bin counts (and NumSmaller and NumLarger) to zero; the number of bins and the bin boundaries remain unchanged.

PDF() computes the probability density function (PDF) for a specified value or bin, and CDF() computes the cumulative distribution function (CDF).
