To format the lines in a line chart, follow the steps below:
Note: If the chart is a combo chart composed by lines and areas/bars, when you set the depth properties for the lines, they will be applied to the areas/bars as well, and vice versa.
Note: For 3-D charts, the Show Data Label checkbox is grayed out. However, you can still see the data labels by moving the mouse pointer over the lines when viewing the report result in view mode or in JReport Web.
See also Format Line dialog for detailed explanation about options in the dialog.
