100% Stacked Bar Chart with Negative Data

C# Example Code

{                
    System.Random r= new System.Random();
    chart.Theme = Theme.Blues;
    chart.XAxis.MajorTickStep = 2;
    chart.Series[0].Type = ChartType.StackedBar;
    chart.Series[1].Type = ChartType.StackedBar;
    chart.Series[2].Type = ChartType.StackedBar;
    chart.Series[3].Type = ChartType.StackedBar;
    for (float f=-360.0f;f<=360.0f;f += 90)
    {
        double a = f * (Math.PI/180);
        double val = (Math.Sin(a*2.5) + Math.Sin(a*3.5)) * 0.5;

        chart.Series[0].Data.Add(new DataPoint(val+1.5, f.ToString()));
        chart.Series[2].Data.Add(new DataPoint(val-1.5, f.ToString()));

        chart.Series[1].Data.Add(new DataPoint(3.5-val, f.ToString()));
        chart.Series[3].Data.Add(new DataPoint(-3.5-val, f.ToString()));
    }                        
}
