How to add a prefix and suffix to the axis labels in the Blazor Chart?

This article explains how to add a prefix and suffix to the axis labels in the Blazor Chart Component.

Adding Prefix and Suffix to Axis Labels in Blazor Chart

The Blazor Chart provides support for formatting axis labels using global formatting options like ‘N’, ‘C’, and ‘P’ through the LabelFormat property of the respective axis (X or Y) which you want to format the axis labels. Additionally, the axis supports the inclusion of prefixes and suffixes to the labels using placeholders such as ${value}K , where “value” represents the axis label, for instance, $20K.

The following code example demonstrates how to add prefix and suffix to the Y-axis labels in the Blazor Chart:

Index.razor

@using Syncfusion.Blazor.Charts

<sfchart>

    <chartprimaryyaxis labelformat="${value}K" rangepadding="ChartRangePadding.Auto">

    <chartprimaryxaxis rangepadding="ChartRangePadding.Auto">

    <chartseriescollection>
        <chartseries datasource="@Data" xname="XValue" yname="YValue" type="ChartSeriesType.Column">
    </chartseries></chartseriescollection>

</chartprimaryxaxis></chartprimaryyaxis></sfchart>

@code {

    public class ChartData
    {
        public double XValue { get; set; }
        public double YValue { get; set; }
    }

    public List<chartdata> Data = new List<chartdata>
    {
        new ChartData { XValue = 10, YValue = 21 },
        new ChartData { XValue = 20, YValue = 24 },
        new ChartData { XValue = 30, YValue = 36 },
        new ChartData { XValue = 40, YValue = 38 },
        new ChartData { XValue = 50, YValue = 54 },
        new ChartData { XValue = 60, YValue = 57 },
        new ChartData { XValue = 70, YValue = 70 },
    };

}
