#Remarks
IChartSeriesLabel properties allow you to configure point label settings. To access these settings, use the PointLabel property in a CustomizeSeriesPoint event handler.
Set the ShowForZeroValues

to hide labels for series points with zero values. Note that this property only affects series that display bars.
#Example
The following example hides labels for bars with zero sales amounts:
<DxChart Data="@SalesData"
CustomizeSeriesPoint="@PreparePointLabel" >
<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" />
</DxChartBarSeries>
<DxChartLegend Position="RelativePosition.Outside"
HorizontalAlignment="HorizontalAlignment.Right" />
</DxChart>
@code {
IEnumerable<SaleInfo> SalesData;
protected override async Task OnInitializedAsync() {
SalesData = await Sales.GetSalesAsync();
}
protected void PreparePointLabel(ChartSeriesPointCustomizationSettings pointSettings) {
pointSettings.PointLabel.ShowForZeroValues = false;
}
