Echarts中的饼图的某块由于数据太小导致占比太小，图形上几乎看不见问题的解决方案

数据过多,且几个比较小的数据在一块扎堆

解决方案 在series中的一个对象中添加属性 minAngle

源码1，元数据部分：

#其中的两个红色加粗的为数值非常小的，在饼图中根据数据占比会非常小，用肉眼几乎看不出来。let echartData = {
    inner: [
        {
            value: 300,
            unit: '件',
            name: '第一检查部'
        },
        {
            value: 100,
            unit: '件',
            name: '第二检查部'
        },
        {
            value: 10,
            unit: '件',
            name: '第三检查部'
        },
        {
            value: 160,
            unit: '件',
            name: '第四检查部'
        },
        {
            value: 1,
            unit: '件',
            name: '第五检查部'
        }
    ],
    outer: [
        {
            value: 100,
            unit: '件',
            name: '第一检查部'
        },
        {
            value: 300,
            unit: '件',
            name: '第二检查部'
        },
        {
            value: 400,
            unit: '件',
            name: '第三检查部'
        },
        {
            value: 400,
            unit: '件',
            name: '第四检查部'
        },
        {
            value: 3,
            unit: '件',
            name: '第五检查部'
        }
    ]
}

　源码2：echart中的series部分

series: [
        //最外层圆环
        
      
       {
           name: '外环',
           type: 'pie',
           minAngle: 10,  //设置扇形的最小占比
           radius: ['50%', '75%'],
           center: ["40%", "50%"],
