How to add an axis dynamically to the Blazor Circular Gauge?

The Blazor Circular Gauge allows us to add axes dynamically during runtime. In this section, we will explain you how to add an axis dynamically in the Circular Gauge using a button click event.

You can create a list of numbers that indicate the maximum value of an axis. The value from this list must be set in the Maximum property of CircularGaugeAxis. The CircularGaugeAxis tag must be used within an iteration condition to add multiple axes. When a number is pushed into the list during the button click event, a new axis is dynamically added to the Circular Gauge component.

The below code example demonstrates how to add an axis dynamically in the Blazor Circular Gauge.

Index.razor

@using Syncfusion.Blazor.CircularGauge;
@using Syncfusion.Blazor.Buttons;

<SfButton CssClass="e-btn e-info" Content="Add Axis" @onclick="AddClick"></SfButton>
<SfCircularGauge>
    <CircularGaugeAxes>
        @foreach (var maximum in AxesMaximum)
        {
            <CircularGaugeAxis Maximum="maximum">
                <CircularGaugeAxisLineStyle Width="2" Color="#9E9E9E" />
                <CircularGaugeAxisMajorTicks Offset="5" />
                <CircularGaugeAxisMinorTicks Offset="5" />
            </CircularGaugeAxis>
        }
    </CircularGaugeAxes>
</SfCircularGauge>



@code {
    private List<int> AxesMaximum = new() { 100 };
   

    public void AddClick()
    {
        AxesMaximum.Add(200);
    }
}

The screenshots below show the output of the above code snippet.
