modifing barchart in script

cheq326

I have a report with Barcharts. A series that shows Q1 data, now I need to update the chart to include Q2 data as well. I was able to add a series using following codes, but its color is grey(I want it to be red), and label shows counts(I want it to be in percentile format). Also need to update the text/color of Legends. I hope I explain it clearly. Please help, thanks!

in beforefactory:
importPackage(Packages.org.eclipse.birt.chart.model.data.impl);
importPackage(Packages.org.eclipse.birt.chart.model.component.impl);
importPackage(Packages.org.eclipse.birt.chart.model.type.impl);
importPackage(Packages.org.eclipse.birt.chart.model.attribute);

//Chart must be named
cht = reportContext.getDesignHandle().findElement("chart1");
mychart = cht.getReportItem().getProperty( "chart.instance" );


//Get the x axis
xAxis =mychart.getAxes().get(0);

//Get the first y axis
yAxis1 = xAxis.getAssociatedAxes().get(0);

{
//create a new series definition for each new series
var sdNew = SeriesDefinitionImpl.create();
//create a new series for each parameter selection
var ls = BarSeriesImpl.create();
ls.getLabel().setVisible(true);
//set bar color

//ls.setRiserOutline(ColorDefinitionImpl.RED());

//Create the query. The row value must correlate with the data set row value
var qry = QueryImpl.create("row[\"NewCol\"]" );
ls.getDataDefinition().add(qry)
sdNew.getSeries().add( ls );
//Add the new series definition to the first y axis
yAxis1.getSeriesDefinitions().add( sdNew );
}

This should set the color:

function beforeDrawDataPoint( dph, fill, icsc )
{
if (dph.getSeriesDisplayValue() == "blah"){
fill.set(255,0,0);
}
}

I believe the legend color can be set in the beforeDrawLegendItem function of the chart.
