BIRT supports a number of different types of charts. Some chart types present certain data better than other types. For example, a line chart can effectively show how numeric data changes over time. A bar chart is a good choice for comparing a limited number of individual items. A colorful pie chart can add interest to a report by showing the size of a small number of items, proportional to the sum.
