AnnotatedTimeline error

[rvsjoen]

I am trying to use the Google Visualization API to provide an annotated timeline visualization. I included a small testcase which demonstrates the error.

Anyone know how I can set the height and width of the container from a 'GWT Visualization' perspective ?
Alternatively other ways of fixing this, I have tried wrapping it in a SimplePanel and setting the size on that but with the same result. I also tried putting it in a Canvas with a configured size.

public class Test implements EntryPoint {

    public void onModuleLoad() {
        final Canvas c = new Canvas();
        c.setHeight("800");
        c.setWidth("1000");
        c.setBackgroundColor("#FF0000");
        VisualizationUtils.loadVisualizationApi(new Runnable() {
            @Override
            public void run() {
                AnnotatedTimeLine t = new AnnotatedTimeLine("800", "500");
                DataTable data = DataTable.create();
                c.addChild(t);
                t.draw(data);
            }
        }, AnnotatedTimeLine.PACKAGE);
        c.draw();
    }
}
