xAxisPrimary.setType(AxisType.DATE_TIME_LITERAL);
xAxisPrimary.setFormatSpecifier(JavaDateFormatSpecifierImpl

// xScale.setMin(DateTimeDataElementImpl.create(longDate1));
// xScale.setMax(DateTimeDataElementImpl.create(longDate2));
// xAxisPrimary.setScale(xScale);
.
.
.
}
I also tried setting outside the scripy, but it doesnt seem to be working.
Thanks in advance,

Can you try a script like:
function beforeGeneration(chart, icsc)
{
importPackage( Packages.org.eclipse.birt.chart.model.data.impl );
importPackage( Packages.org.eclipse.birt.chart.util );
xAxis = chart.getBaseAxes()[0];
yAxis = chart.getOrthogonalAxes( xAxis, true)[0]
scale = xAxis.getScale();
scale.setMin( DateTimeDataElementImpl.create( new CDateTime(2001,1,1) ) );
scale.setMax( DateTimeDataElementImpl.create( new CDateTime(2009,1,10) ) );
}
