Dynamic marker on the y axis of a Chart

Hello everyone,

I try to put a dynamic marker on the y axis of a Chart (Gantt) based on the current date.

I can add a static marker, but not a dynamic. Can anyone help me ?

Thanks and regards,

Dr. Maboule,

You can use the following script to add a marker line based on a date to a Gantt chart:

importPackage( Packages.org.eclipse.birt.chart.model.component.impl );
importPackage( Packages.org.eclipse.birt.chart.model.data.impl );
importPackage( Packages.org.eclipse.birt.chart.util );

function beforeGeneration( chart, icsc )
{
xAxis = chart.getPrimaryBaseAxes()[0];
yAxis = chart.getPrimaryOrthogonalAxis(xAxis);
markerLine = MarkerLineImpl.create(yAxis, DateTimeDataElementImpl.create(new CDateTime(2005, 3, 1)));
markerLine.getLabel().setVisible(false);
yAxis.getMarkerLines().add(markerLine);

}

Hope this helps,

P.
