I would like to know how to refresh a chart if we want to change "in live" some piece of data. I mean for instance, I have a chart with a TaskSeries which appears on 3 years and I would like to change 3 years by 5 years. I want the chart to change immediately.
Is there some kind of update chart or something like that ?
I know that you could say "get your TaskSeries, do your changes and it will be refreshed automatically" but my TaskSeries are generated and I cannot easily change these ones. That's why I would like to find a way to recalculate and to rebuild the whole chart.
The add()
method of TaskSeries
automatically sends a SeriesChangeEvent
to all registered listeners, e.g. CategoryPlot
. In this example, DynamicTimeSeriesCollection
implements SeriesChangeEvent
. In this case, the chart's XYPlot
is a registered listener.
