Using Actuate BIRT Viewers : Modifying charts : Modifying charts in Interactive Viewer : Changing chart subtype
 
Changing chart subtype
Area charts, bar charts, cone charts, line charts, pyramid charts, and tube charts have a stacked subtype and a percent stacked subtype. In a stacked chart, the data points from one value series are arranged on top of the data points of another series. You can choose the percent stacked subtype to show the contribution of individual items to the whole.
If a type of chart offers subtypes, you can change the subtype in Interactive Viewer. Many chart types offer two‑dimensional subtypes, in which the chart shape appears flat against the chart background. You can also display some charts in two dimensions with depth, or three dimensions. A chart with depth appears to have added dimension.
How to modify the chart subtype
1 Select the chart to highlight it. From the context menu choose Change Subtype.
2 On Chart Subtype choose an option from the available subtypes. Choose OK to apply your selection.
