Suppose the data is being updated continuously (every 0.1 second or some
small interval), is it possible to refresh the chart every time the data is
updated?
I guess we could just create a new chart every time. But the chart would
keep flashing which would be annoying.
Any solution/idea?
Thanks

Hi Feng,
Yes it's possible, you don't need to recreate a chart everytime. You can
reuse the same chart, update the data, and then call "refresh" (not build),
and then render. Refresh will skip layout computations (not needed if you
only change the data).
There is an example in org.eclipse.birt.chart.examples :
SwingLiveChartViewer
Thanks,
David
