How to individually zoom Y axis or X axis in the Blazor Chart?

This article explains how to customize the zoom functionality to individually zoom the y-axis or x-axis in the Blazor Chart Component.

Adjusting Zoom Mode in Blazor Chart Component

Blazor Chart provides support for customizing the zoom mode by using the Mode property in ChartZoomSettings. This property determines whether the chart can scale along the horizontal or vertical axes. The default value of the mode is XY (both axes).

Mode property in includes the following zooming mode option:

• X - Allows us to zoom the chart horizontally.
• Y - Allows us to zoom the chart vertically.
• XY - Allows us to zoom the chart both vertically and horizontally.

In the below code example, the Mode property is set to X. This will allow you to zoom only along X-axis while the zooming along Y axis is restricted.

Index.razor

@using Syncfusion.Blazor.Charts

<SfChart Title="Sales History of Product X">

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

   <ChartZoomSettings EnableSelectionZooming="true" Mode="ZoomMode.X"></ChartZoomSettings>

   <ChartSeriesCollection>
       <ChartSeries DataSource="@SalesReports" XName="X" YName="YValue" Type="ChartSeriesType.Column"></ChartSeries>
   </ChartSeriesCollection>

</SfChart>

@code {
   public class ChartData
   {
       public string X { get; set; }
       public double YValue { get; set; }
   }

   public List<ChartData> SalesReports = new List<ChartData>
   {
       new ChartData { X= "USA", YValue= 46 },
       new ChartData { X= "GBR", YValue= 27 },
       new ChartData { X= "CHN", YValue= 15 },
       new ChartData { X= "UK", YValue= 20 },
       new ChartData { X= "AUS", YValue= 50 },
       new ChartData { X= "IND", YValue= 26 },
       new ChartData { X= "DEN", YValue= 30 },
       new ChartData { X= "MEX", YValue= 26 },
   };
}
