Set chart meter region at runtime

Hello,

I'm tryin to set the start value and end value of regions in a meter chart in the beforedrawserie function but I got the error "TypeError: Cannot find function getDial in object class org.eclipse.birt.chart.model.component.impl.SeriesImpl"

for this code : function beforeDrawSeries( series, isr, icsc )
{
importPackage(Packages.org.eclipse.birt.chart.model.component.impl.*);
importPackage(Packages.org.eclipse.birt.chart.model.data.impl);
importPackage(Packages.org.eclipse.birt.chart.model.attribute);
importPackage(Packages.org.eclipse.birt.chart.model.attribute.impl);
series.getClass().getDial().getDialRegions().add(region);
. .
}

I tried series.getDial() , series.getClass().getComponent().getDial(). It doesn't work.

If you have an idea , I ll appreciate.

Hi egau, here is an example to add a region to a BIRT meter chart at runtime using scripting.<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
function beforeGeneration( chart, icsc )
{
importPackage(Packages.org.eclipse.birt.chart.model.component.impl);
importPackage(Packages.org.eclipse.birt.chart.model.attribute.impl);
importPackage(Packages.org.eclipse.birt.chart.model.attribute);
importPackage(Packages.org.eclipse.birt.chart.model.data.impl);

var firstAxis = chart.getSeriesDefinitions().get(0).getSeriesDefinitions().get(0).getRunTimeSeries().get(0).getDial();

var firstRange = DialRegionImpl.create();
firstRange.setFill(ColorDefinitionImpl.RED());
firstRange.setStartValue( NumberDataElementImpl.create( 0 ) );
firstRange.setEndValue( NumberDataElementImpl.create( 2 ) );
firstAxis.getDialRegions().add(firstRange);

var secondRange = DialRegionImpl.create();
secondRange.setFill(ColorDefinitionImpl.YELLOW());
secondRange.setStartValue( NumberDataElementImpl.create( 2 ) );
secondRange.setEndValue( NumberDataElementImpl.create( 5 ) );
firstAxis.getDialRegions().add(secondRange);

var thirdRange = DialRegionImpl.create();
thirdRange.setFill(ColorDefinitionImpl.GREEN());
thirdRange.setStartValue( NumberDataElementImpl.create( 5 ) );
thirdRange.setEndValue( NumberDataElementImpl.create( 6 ) );
firstAxis.getDialRegions().add(thirdRange);

}
</pre>

Can we get values from dataset and use it in script? for example range values from data set.?
