Bar charts present each series as a horizontal bar, and group the bars by category. The x-axis values determine the lengths of the bars, while the y-axis displays the category labels. With a bar chart, you can select from the following subtypes.

Bar

 Compares values of items across categories.

Stacked Bar

A bar chart with two or more data series stacked one on top of the other that shows how each value contributes to the total.

Percent Stacked Bar

A bar chart with two or more data series stacked one on top of the other to sum up to 100% that shows how each value contributes to the total with the relative size of each series representing its contribution to the total.
