Currently I do not believe this is supported. Can you post a
screenshot of what you want it to look like, and I may be able to show
you another way to do this.

This is supported if you specify a new series definition for the
unstacked series. You can not mix stacked and unstacked in the same
series definition.
public Chart createStackedBar()

cwaBar.getBlock().setBackground(ColorDefinitionImpl.WHITE());
cwaBar.getBlock().getOutline().setVisible(true);
Plot p = cwaBar.getPlot();
p.getClientArea().setBackground(ColorDefinitionImpl.create(255,
255,
225));
// Title
cwaBar.getTitle()

.getCaption()
