How to Display Numeric Axis Labels in Blazor Charts?

This article explains how to display numeric axis labels in integer after zooming in Blazor Charts.

Displaying axis labels in integer after zooming

Blazor Charts provides an option to display the numeric axis labels only in integer after performing zooming in chart using OnAxisActualRangeCalculated event.

This can be achieved by rounding the Interval value of numeric axis on OnAxisActualRangeCalculated event by checking the argument axis name is equal to PrimaryYAxis. This will render intervals in integer even after zooming the chart.

The below code example demonstrates how to display numeric axis labels in integer.

Index.razor

@using Syncfusion.Blazor.Charts
<SfChart>
   <ChartEvents OnAxisActualRangeCalculated="RangeCalculated"></ChartEvents>
   <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category"></ChartPrimaryXAxis>
   <ChartSeriesCollection>
       <ChartSeries DataSource="@Sales" XName="Month" YName="SalesValue" Type="Syncfusion.Blazor.Charts.ChartSeriesType.Column">
       </ChartSeries>
   </ChartSeriesCollection>
   <ChartZoomSettings EnableSelectionZooming="true"></ChartZoomSettings>
</SfChart>

@code {
   public void RangeCalculated(AxisRangeCalculatedEventArgs Args)
   {
       if (Args.AxisName == "PrimaryYAxis")
       {
          Args.Interval = Math.Round(Args.Interval);
       }
   }

   public class SalesInfo
   {
       public string Month { get; set;}
       public double SalesValue { get; set;}
   }

   public List<SalesInfo> Sales = new List<SalesInfo>
   {
       new SalesInfo { Month = "Jan", SalesValue = 35 },
       new SalesInfo { Month = "Feb", SalesValue = 28 },
       new SalesInfo { Month = "Mar", SalesValue = 34 },
       new SalesInfo { Month = "Apr", SalesValue = 32 },
       new SalesInfo { Month = "May", SalesValue = 40 },
       new SalesInfo { Month = "Jun", SalesValue = 32 },
       new SalesInfo { Month = "Jul", SalesValue = 35 }
   };
}
