histogram is a graphical display of tabulated frequencies. It shows what proportion of cases fall into each of several categories. There is a difference between a histogram and a bar chart in the sense that it is the area of the bar that dictates the value, not the height, which is a very important difference particularly when the variables are not all the same width.
