Fitting the Linear Gauge to the control

The Linear Gauge component is rendered with margin by default. To remove the margin around the Linear Gauge, the AllowMargin property in ejs-lineargauge is set as false.

CSHTML

@using Syncfusion.EJ2.LinearGauge

<ejs-lineargauge id="linear" Orientation="Horizontal" Background="skyblue" AllowMargin="false" Height="100%" Width="100%">
    <e-lineargauge-border Width="3" Color="red"></e-lineargauge-border>
    <e-lineargauge-margin Left="0" Right="0" Top="0" Bottom="0"></e-lineargauge-margin>
    <e-lineargauge-axes>
        <e-lineargauge-axis></e-lineargauge-axis>
    </e-lineargauge-axes>
</ejs-lineargauge>

Gauge-margin.cs

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using EJ2_Core_Application.Models;
using Newtonsoft.Json;
using Syncfusion.EJ2.Charts;
using Syncfusion.EJ2.LinearGauge;


namespace EJ2_Core_Application.Controllers
{
    public class HomeController : Controller
    {
        public IActionResult Index()
        {
            return View();
        }
    }
