It's useful for getting a quick look at the distribution of values of the selected metric column. The more values fall in a range, the higher the bar. In the above chart you can see that a typical procedures name consists of 7-16 characters. Shorter and longer names are fewer. There are no names with just 1 or 2 characters.
