Is it possible to update a chart from a button click? If so is there any sample code regarding this?

Thanks

Can you give some more detail on how you are running the chart. In the
WebViewer? API? When you want it to update do you just want to re-run
the report and get the new data?

I am running via the API on an SWT application. I understand that the chart can be refreshed using a callback implementation by adding triggers. But is it possible to do this externally eg: draw a trendline via an SWT button action. If so how do I link the button action in order to refresh the chart after I draw the line?

If you checkout the org.eclipse.birt.chart.examples plugin it contains
several SWT example where an update button is used. Look at
SwtChartViewerSelector.java
SwtLiveChartViewer.java
SwtInteractivityViewer.java
