Okay, everybody, I'll do that.
Thanks

Hello, I am wondering what an annotation is. I have downloaded the source code of JFreeChart, and found that a ChartArea can be customized Also, I've found some places where annotation can have a setX(), setY() public method, Another area to look at is the Rectangle2D part, just wondering which part...

There's nothing built into JFreeChart to do any transition effects. You could investigate some of these suggestions: http://stackoverflow.com/questions/11425274/adding-animation-transitions-to-java-swing-containers Hello David, Just wondering how to get the "bar" object from the category plot. So t...

BTW, I reverted to 1.0.5 to no avail

I changed to chart.addProgressListener(new ChartProgressListener() { private boolean animate = true; public void chartProgress(final ChartProgressEvent event) { if (event.getType() == ChartProgressEvent.DRAWING_FINISHED ) { //System.out.println("Event working"); if ( animate ) { } } } }); Which prop...

Yes, subject to one proviso. Every time you update a dataset belonging to a chart, it triggers a sequence of events that results in the ChartPanel being repainted. If you update the dataset frequently (5 times per second, say) the chart will appear to be "animated". The proviso is that each update ...

When the user enters the frame, displays the chart, the portions of the chart are gradually fly-in, just like powerpoint,
How do I achieve that in JFreeChart?
Thanks
Jack

Any help would be greatly appreciated!

I found out that if I don't fireDataChanged to the dataset, the jumpy behaviour is not exhibited, but if I don't do it,
the dataset will be mixed up. The chart will contain errors consisting of data of 2 different datasets.
Thanks

How do I update a JFreeChart live?
When a user adds data to the data model, I'd like to change the chart straight away
Do you have any listeners for this usage?
Thanks
Jack

Thanks David, Rather than straight diving into books, I searched a few forums on this. I should have done something like this this.setContentPane(chartPanel); And the "Canvas" for the chart should derive from ApplicationFrame. I saw both of the example methods get called. But there is still nothing ...
