Remarks

Set the ShowForZeroValues property to false to hide labels for series points with zero values. Note that this property only affects series that display bars.

The following example hides the label for the bar with a zero sales amount value:

<DxChart Data="@SalesData">
    <DxChartTitle Text="Sales amount, $" />
    <DxChartBarSeries Name="2017" 
                      Filter="@((SaleInfo s) => s.Date.Year == 2017)"
                      ArgumentField="@(s => s.City)" 
                      ValueField="@(s => s.Amount)"
                      SummaryMethod="Enumerable.Sum">
         <DxChartSeriesLabel Visible="true"
                             Position="RelativePosition.Outside"
                             ShowForZeroValues="false"/>
    </DxChartBarSeries>
    <DxChartLegend Position="RelativePosition.Outside"
                   HorizontalAlignment="HorizontalAlignment.Right" />
</DxChart>

@code {
    IEnumerable<SaleInfo> SalesData;

    protected override async Task OnInitializedAsync() {
        SalesData = await Sales.GetSalesAsync();
    }
}
