"WebbWhat is a histogram? A histogram is a chart that plots the distribution of a numeric variable’s values as a series of bars. Each bar typically covers a range of numeric values called a bin or class; a bar’s height indicates the frequency of data points with a value within the corresponding bin. " - Histogram shifting

Webbposed to solve the above-mentioned problems. Rather than the use of the histogram shifting with peak points and zero points in Chang’s method [1], the histogram shifting with tree structure [18] is employed in the proposed scheme. In general, the di erences between two adjacent data in a same attribute are usually small.
