https://echarts.apache.org/examples/zh/editor.html?c=gauge 你把那个仪表盘改吧改吧，就差不多了

自根据需求改一改
```option = {
tooltip: {
formatter: '{a}
{b} : {c}%'
},
toolbox: {
feature: {
restore: {},
saveAsImage: {}
}
},
series: [
{
name: '业务指标',
type: 'gauge',
detail: {formatter: '{value}%'},
data: [{value: 50, name: '完成率'}]
}
]
};

setInterval(function () {
option.series[0].data[0].value = (Math.random() * 100).toFixed(2) - 0;
myChart.setOption(option, true);
},2000);
