Adding Charts and Graphics
to Reports
All the reports we have seen so far contain only textual data. JasperReports has the
capability to create reports with graphical data in them, including simple geometric
shapes, images, and charts. Adding graphical representation of the data makes it
easier to visualize. Moreover, adding images and other graphical elements allows

The following topics will be covered in this chapter:
Adding simple geometrical shapes to a report
Adding images to a report
Adding different types of 2-D and 3-D charts to a report
