Example

This example shows how to provide data for the ChartView series.

C#

public class MainViewModel {
    public List<Gdp> Gdps { get; }
    public IList<GdpValue> GdpValueForChina => Gdps[0].Values;

    public MainViewModel() {
        Gdps = new List<Gdp> {
            new Gdp(
                    "China",
                    new GdpValue(new DateTime(2017, 1, 1), 19.391),
                    // ...
                    new GdpValue(new DateTime(2007, 1, 1), 14.478)
                    ),
            };
    }
}
// ...
public class GdpValue {
    public DateTime Year { get; }
    public double Value { get; }

    public GdpValue(DateTime year, double value) {
        this.Year = year;
        this.Value = value;
    }
}
