What determines the height of each bar in a histogram?

The height of each bar in a histogram represents the frequency or count of data points that fall within a specific range, known as a bin or interval. The width of each bin is uniform, and the total area of the histogram reflects the total number of observations. If the bins are wider, the height of the bars will generally be lower, assuming the same number of data points, while narrower bins may yield taller bars due to a higher concentration of data points. Thus, the height is determined by both the number of observations in each bin and the bin width.
