Hello,
I am generating a report using the DE API (BIRT 3.7.1) but i am stuck at customizing the Palette used by my PieGraph.
The only way i have found to manage the color palette is through the following code:
SeriesDefinition segroup = SeriesDefinitionImpl.create();
segroup.getSeriesPalette().update(0);
I can only update(int) or shift(int) the Palette!
I need to specify the colors to be used in my Palette for my pieChart as well as specify through DE API some gradients for each palette entry.
Any luck that somebody might know how to do this?
Many thanks,
Best Regards,
Jean-Baptiste

Try:
segroup.getSeriesPalette( ).getEntries( ).clear( );
segroup.getSeriesPalette().getEntries().add( GradientImpl.create(
ColorDefinitionImpl.create(220,237,248),
ColorDefinitionImpl.create(80,166,218), 0, false));
segroup.getSeriesPalette().getEntries().add( GradientImpl.create(
ColorDefinitionImpl.create(255,213,213),
ColorDefinitionImpl.create(242,88,106), 0, false));
segroup.getSeriesPalette().getEntries().add( GradientImpl.create(
ColorDefinitionImpl.create(255,247,213),
ColorDefinitionImpl.create(232,172,57), 0, false));
segroup.getSeriesPalette().getEntries().add( GradientImpl.create(
ColorDefinitionImpl.create(213,255,213),
ColorDefinitionImpl.create(128,255,128), 0, false));
segroup.getSeriesPalette().getEntries().add( GradientImpl.create(
ColorDefinitionImpl.create(213,255,255),
ColorDefinitionImpl.create(64,128,128), 0, false));
segroup.getSeriesPalette().getEntries().add( GradientImpl.create(
ColorDefinitionImpl.create(226,226,241),
ColorDefinitionImpl.create(128,128,192), 0, false));
