public class OpenFlashChartComponent
extends ComponentBase

This component is a contribution from Nick Goodman and Tom Qin, it conforms to the ChartComponent API. Please see the wiki for details on this component. The component uses open-flash-chart-full-embedded-font.swf, found at http://www.ofc2dz.com/, which is a patched version of Open Flash Chart 2, found at http://teethgrinder.co.uk/open-flash-chart-2/ note: onclick events are only partially implemented, due to limitations of OFC. In future releases of OFC, this should be revisited. Backlog: - y2_legend - barline right axis title, would need to update OFC4J - horizontal stacked bars http://www.ofc2dz.com/OFC2/examples/HorizontalStackedBars.html - styled stacked bars (would require impl in OFC) - dial chart (would require impl in OFC) - XY Line Chart - XY Area Chart - onclick / link support (would require enhancements to OFC) - allow override of dataFunction name - review colors, move into config file for both jfree and ofc? - area stacked
