echarts 仪表盘图展示百分比

效果图如下：

背景图一加，效果就好看多了

代码：

        let myChart = echarts.getInstanceByDom(
			document.getElementById('verificationChart')
		)
		if (myChart == null) {
			// 如果不存在，就进行初始化
			myChart = echarts.init(document.getElementById('verificationChart'))
		}
		const gaugeData = [
			{
				value: 74,
				name: '核查率',
				title: {
					offsetCenter: ['0%', '20%'],
				},
				detail: {
					valueAnimation: true,
					offsetCenter: ['0%', '-15%'],
				},
			},
		]
		let option = {
			series: [
				{
					type: 'gauge',
					radius: 162,
					startAngle: 90,
					endAngle: -270,
					pointer: {
						show: false,
					},
					progress: {
						show: true,
						// 多组数据时进度条是否重叠
						overlap: false,
						// width: 20,
						roundCap: true,
						clip: false,

						itemStyle: {
							borderWidth: 0,
							color: {
								type: 'linear',
								x: 0,
								y: 0,
								x2: 0,
								y2: 1,
								colorStops: [
									{
										offset: 0,
										color: '#009EF8', // 0% 处的颜色
									},
									{
										offset: 1,
										color: '#30FFFF', // 100% 处的颜色
									},
								],
							},
						},
					},
					axisLine: {
						// 是否显示仪表盘轴线
						show: false,
						lineStyle: {
							// 仪表盘轴线宽度也要设置,否则只设置进度条宽度就不生效
							width: 20,
						},
					},
					splitLine: {
						show: false,
					},
					axisTick: {
						show: false,
					},
					axisLabel: {
						show: false,
					},
					data: gaugeData,
					title: {
						fontSize: 26,
						color: '#fff',
					},
					detail: {
						fontSize: 56,
						color: '#fff',
						fontFamily: 'YouSheBiaoTiHei',
						formatter: '{value}%',
					},
				},
			],
		}

		myChart.setOption(option)
		window.addEventListener('resize', () => {
			myChart.resize()
		})
