Peter,
Are you using the chart engine api to run the charts?

I am not sure this will help but you can define your own action renderer
for the chart engine like:
gcs = gr.build(dServer, cm, bo, null, null, null);
gcs.getRunTimeContext().setActionRenderer( new MyActionRenderer());
dRenderer.setProperty(IDeviceRenderer.UPDATE_NOTIFIER,
new EmptyUpdateNotifier(cm, gcs.getChartModel()));
Then the action render should extend the ActionRendererAdapter class like:
import org.eclipse.birt.chart.render.ActionRendererAdapter;
import org.eclipse.birt.chart.computation.DataPointHints;
import org.eclipse.birt.chart.event.StructureSource;
import org.eclipse.birt.chart.event.StructureType;
import org.eclipse.birt.chart.factory.IDataRowExpressionEvaluator;
import org.eclipse.birt.chart.model.attribute.ActionType;
import org.eclipse.birt.chart.model.attribute.TooltipValue;
import org.eclipse.birt.chart.model.attribute.URLValue;
import org.eclipse.birt.chart.model.data.Action;
import org.eclipse.birt.chart.render.ActionRendererAdapter;
import org.eclipse.birt.chart.util.ChartUtil;
/**
* Simple implementation for IActionRenderer
*/
public class MyActionRenderer extends ActionRendererAdapter {
public void processAction( Action action, StructureSource source )
{
if ( ActionType.SHOW_TOOLTIP_LITERAL.equals( action.getType( ) ) )
{
TooltipValue tv = (TooltipValue) action.getValue( );
if ( StructureType.SERIES_DATA_POINT.equals( source.getType( ) ) )
{
final DataPointHints dph = (DataPointHints) source.getSource( );
String MyToolTip = "My Value is " + dph.getDisplayValue() + "--"
+dph.getBaseDisplayValue();
tv.setText( MyToolTip );
}
}
}
}

I know the chart engine when used within a report can invoke a client
side script when a data point is clicked. I believe you may be able to
setup the chart engine to do this in your app. If you had a simple app
that shows the problem that you could share, we may be able to help.

Hi,
This are my two classes.
The class SwtLiveChartViewer is copied from a tutorial.
In the class LineChart i am adding the trigger.
bs1.getTriggers().add(TriggerImpl
.create(TriggerCondition.ONMOUSEDOWN_LITERAL, ActionImpl
.create(ActionType.SHOW_TOOLTIP_LITERAL,
TooltipValueImpl.create(500, null))));
When i'm clicking on a point the tooltipp is displayed. In fact i only want to call a function, which i can defined, when the user clicks on a point.
Thanks
Peter

Can you try using the generated chart state object to get the plot
computations like: (Note this only gets the auto scale of the orthogonal
axis) The x-axis will have a discreet number of points as defined in you
dataset. Have a look at the bottom to see how to access these points.
Axis xAxis = ((ChartWithAxes) chart).getPrimaryBaseAxes()[0];
Axis yAxis = xAxis.getAssociatedAxes().get(0);
SeriesDefinition xSerieDef = xAxis.getSeriesDefinitions().get(0);
SeriesDefinition ySerieDef = yAxis.getSeriesDefinitions().get(0);
Series ySerie = ySerieDef.getRunTimeSeries().get(0);
Object min =
gcs.getComputations().getSeriesRenderingHints(ySerieDef,ySerie).getOrthogonalScale().getMaximum(
);
Object max =
gcs.getComputations().getSeriesRenderingHints(ySerieDef,ySerie).getOrthogonalScale().getMinimum(
);
//x and y data points
Object orthodp1 =
gcs.getComputations().getSeriesRenderingHints(ySerieDef,ySerie).getDataPoints()[0].getOrthogonalValue();
catdp1 =
gcs.getComputations().getSeriesRenderingHints(ySerieDef,ySerie).getDataPoints()[0].getBaseValue();
int xaxisdpsize =
gcs.getComputations().getSeriesRenderingHints(ySerieDef,ySerie).getDataPoints().length;
