<DxChart Data="@GetData()">

    <DxChartBarSeries ArgumentField="@((DataPoint s) => s.Argument)" ValueField="@((DataPoint s) => s.Value)" />
</DxChart>

@code {
    List<DataPoint> GetData() {
        List<DataPoint> result = new List<DataPoint>(6);
        result.Add(new DataPoint("2019-03-10", "11.5"));
        result.Add(new DataPoint("2019-03-08", "10.2"));
        result.Add(new DataPoint("2019-03-07", "8.3"));
