In a normal bar graph, each bar represents one value. In a stacked bar graph, each bar has a number of values, stacked on top of each other. So a bar can show how a total is broken down. So each bar could represent a year, with the amounts for each month indicated by different parts of that one bar.

pictograph, bar graph, and a line graph
Bar graphs and line graphs.
Bar graphs can compare two sets of data, as well as line graphs and circle graphs. To better improve my answer, double line graphs and double bar graphs compare two sets of data. Circle graphs cannot however, because they compare parts of a whole instead of, as a bar graph would, the amount of something. A circle graph is also incapable of showing data growth over a period of time, as line graphs do. All in all, circle graphs cannot compare to sets of data, and bar graphs and line graphs must be doubled to do so.
