RE: STACKED BARS

Yes, this is actually possible in the latest Alpha 1.0 CVS release. 

So from the test/StackedBarTestDriver.java code base if we pass the
following data points:

		double[][] data = {{-280, 16, -150, 90, 60, 200, 150, 60 },
{80, 216, -10, 30, 15, 90, 150, 87 } };
		Paint[] paints = {Color.yellow, Color.blue };
		String[] legendLabels = {"Test Legend Label", "second set"};
		AxisChartDataSet axisChartDataSet = new AxisChartDataSet(
data, legendLabels, paints, ChartType.BAR_STACKED, stackedBarChartProperties
);

		String[] axisLabels = {"1900", "1950", "2000", "2050",
"3000", "3050", "4000", "4050" };
		IAxisDataSeries dataSeries = new DataSeries( axisLabels,
"Cookies", "Years", null );
		dataSeries.addIAxisPlotDataSet( axisChartDataSet );


		ChartProperties chartProperties = new ChartProperties();
		AxisProperties axisProperties = new AxisProperties( false );

		DataAxisProperties yAxis = (DataAxisProperties)
axisProperties.getYAxisProperties();
		yAxis.setShowZeroLine(true);

We get the attached chart:
