10. Add and move/re-locate annotation jfree.orgInitially, I made annotations immutable because I didn't want the overhead of event listeners to notify the chart whenever an annotation changes, in order to trigger the automatic chart repainting. You'll notice that now the classes aren't really immutable (you can modify some attributes), but there is also still no event notification. This needs tidying up. Perhaps adding event notification, and ... |

27. Annotations+refreshing jfree.orgThe XYPlot.addAnnotation() method is firing a PlotChangeEvent, so I'd expect this to trigger the required repaint. Where are you displaying your chart, and what is the relationship between the chart you display and your 'ChartEditor' instance?
