Remarks

The DxChart component compares each point in a financial series to the previous point. You can use the DxChartFinancialReduction object to highlight points where values decreases.

Use the Level property to specify which values (prices) of a stock are compared.

The following example uses a radio group to switch between compared prices (reduction levels):

<div>
    <label>Reduction Level:</label>
    <DxRadioGroup Items="@(Enum.GetValues(typeof(ChartFinancialReductionLevel)).Cast<ChartFinancialReductionLevel>())"
                  @bind-Value="@ReductionLevel" />
</div>
<DxChart @ref="@chart"
         Data="@stockData"
         Width="100%">
    <DxChartLegend Position="RelativePosition.Outside" />
    <DxChartCandlestickSeries OpenField="(StockDataPoint sdp)=>sdp.Open"

                              CloseField="sdp=>sdp.Close"
