A Histogram shows history representation of the distribution of numerical data. It is an estimate of the probability distribution of a continuous variable (quantitative variable).
The data is grouped into bins, that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval.
Customize the number of bins, whether to use frequency or density, and the data colors.
