Look at this. The problem is related with an antialiasing effect. The solution is not easy.

Heyy Vegeta now you will fly in sky ... I have a solution for your problem.

Override the StackedAreaRenderer to draw the path in single path. Basically the chart is drawn by combining two polygons, the polygons are alternate left and right so if you make left = right polygon there will not be any gaps. It worked out for me, you also give a try. I hope your boss will be happy now.

Here is the trick

GeneralPath left = new GeneralPath();
GeneralPath right = left;

Works fine. This code has to be replaced in the class `StackedXYAreaRenderer2`. — Thomas Arnaud, Sep 01 '16 at 13:51

Follow this lines:

JFreeChart objChart = ChartFactory.createStackedBarChart(
                title, 
                titleX, 
                titleY, 
                objDataset, 
                PlotOrientation.VERTICAL, 
                true, 
                true, 
                false 
);

CategoryPlot plot = (CategoryPlot) objChart.getPlot();

BarRenderer renderer = ((BarRenderer) plot.getRenderer());
renderer.setBarPainter(new StandardBarPainter());

StandardBarPainter Style dont have "white line"
