A % Area chart is very similar to an Area chart, however, the shaded areas are based on percentages rather than amounts (the Y-axis displays the percentage from 0 to 100% rather than the total amount). See the Area chart page for more information.
% Area charts provide a different way to view the proportional areas. They also have the benefit of tooltips showing the values in percentage form, which display when you hover over the data points.
