Unable to cast object of type 'System.Decimal' to type 'System.Double'.

[Andreas]

StockCharts can tagek decimal values but Chart can not.

candle data like open/close/... is decimal in the DataSource.

Is it possible to use decimal values in Chart?

<!-- does not work => Unable to cast object of type 'System.Decimal' to type 'System.Double'. -->

    <SfChart>

        <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category" />

        <ChartSeriesCollection>

            <ChartSeries DataSource="@AdvancedDataSource" 

                        XName=@nameof(CandleDataAdvanced.Time) 

                        High=@nameof(CandleDataAdvanced.High) 

                        Low=@nameof(CandleDataAdvanced.Low) 

                        Open=@nameof(CandleDataAdvanced.Open) 

                        Close=@nameof(CandleDataAdvanced.Close) 

                        Type="ChartSeriesType.Candle">

            </ChartSeries>

        </ChartSeriesCollection>

    </SfChart>

<!-- works -->

    <SfStockChart>

        <StockChartSeriesCollection>

            <StockChartSeries DataSource="@AdvancedDataSource" 

                            XName=@nameof(CandleDataAdvanced.Time) 

                            High=@nameof(CandleDataAdvanced.High) 

                            Low=@nameof(CandleDataAdvanced.Low) 

                            Open=@nameof(CandleDataAdvanced.Open) 

                            Close=@nameof(CandleDataAdvanced.Close)

                            Volume=@nameof(CandleDataAdvanced.Volume)

                            Type="ChartSeriesType.Candle"></StockChartSeries>

        </StockChartSeriesCollection>

    </SfStockChart>

t

(ChartSeries series, StockChartStockEvent stockEvent)
