            public double gold;
            public double silver;
            public double bronze;
        }

Combination Series

Combination of different types like Line, column etc, can be rendered in a chart.

Bar series cannot be combined with any other series as the axis orientation is different from other series.

Enable Complex Property in Series

By setting enableComplexProperty value as true in series you can bind complex data to the chart.
