If you use Visualizations For Vaadin you can create a Column Chart and one of the options that you set is isStacked

Hi,

Unfortunately, the Vaadin Timeline does not at the moment feature stacked graphs.

But since all bar graphs in the Vaadin Timeline are rendered on top of each other you can sort of solve it by creating new data sources from the real ones where you sum the data values up. It isn't a very pretty solution though :(

If you would like to see this feature included in future versions of the Vaadin Timeline please create a feature ticket at http://dev.vaadin.com or http://vaadin.uservoice.com/ and it might get included.

Code for a stacked column chart using the add on

ColumnChart cc = new ColumnChart();
        cc.setOption("is3D", true);
        cc.setOption("isStacked", true);
        
        
        cc.addXAxisLabel("Year");
        cc.addColumn("Expenses");
        cc.addColumn("Sales");
        cc.addColumn("Stock");
// Values in double are Expenses, Sales, Stock
        cc.add("2004", new double[]{100,200,320});
        cc.add("2005", new double[]{75,100, 250});
        cc.add("2006", new double[]{32,234, 75});
        cc.add("2007", new double[]{25,253,4});
        cc.add("2008", new double[]{343,12,260});
        cc.setSizeFull();

Thank you for your answers. I will create a request for a new chart type ;-)

Also check BarGraph add-on.

Also check VisualizationsForVaadin allows stacked Column and Bar charts.
