It usually has a value less than or equal to one, and defaults to 0.5.Histogram is a kind of a bar chart that is used for representing statistical information by how a bar looks based on the probability distribution i.e. the complete of class intervals (grouped set of data) and frequency distribution on x and y axis. Histograms also has bins which are the difference between the frequency distribution values.
