划分10个区间精确显示金额单位和金额，通过echarts显示金额并控制echarts金额最大值

　　通过传入format_amount方法中金额，获取处理后的数据，考虑到单位有万亿元，亿元，万元，元。

const format_amount = (amount) => {
    if (amount >= 1000000000000 && amount < 10000000000000000) {
        return [(amount / 1000000000000).toFixed(2), "万亿元", 'patent_evaluation_price_wmillion'];
    } if (amount >= 100000000 && amount < 1000000000000) {
        return [(amount / 100000000).toFixed(2), "亿元", 'patent_evaluation_price_million'];
    } else if (amount >= 10000 && amount < 100000000) {
        return [(amount / 10000).toFixed(2), "万元", 'patent_evaluation_price_tenyuan'];
    }if (amount < 10000 && amount > 0) {
        return [amount, "元", 'patent_evaluation_price_yuan'];
    }
}

　　例如金额分别为 7117559800、94729336

            }
    showPriceZHChart.value = true;
}

其中 priceZHOption 是echarts的options配置项

// 专利评估-专利价值总和
export const petantPriceZHOption = {
    grid:{
      left:0,
      right:0,
      top:10,
      bottom:40
    },
    tooltip:{
      // 触发类型，item 表示鼠标悬浮在数据项上时触发提示
      trigger: 'item',
      // 提示框的格式化函数，自定义提示框的显示内容
      formatter: '{a} <br/>: {c}{b}'
    },
    series: [
      {
        name: '企业专利价格总和',
        type: 'gauge',
        startAngle: 90,
        endAngle: -270,
        min: 0,
        max: 100,
        center : ['50%', '44%'],
        radius :'88%',
        splitNumber: 12,
        itemStyle: {
          color: '#fff',
          shadowColor: 'rgba(0,138,255,0.45)',
          shadowBlur: 16,
          shadowOffsetX: 2,
          shadowOffsetY: 2
        },
        progress: {
          show: true,
          roundCap: true,
          color:'#0DDAFE',
          width:14,
        }, 
        axisLine: {
          roundCap: true,
          lineStyle: {
            width: 14,
            color:[
              [0.1, '#0665D9'],
              [1, '#0665D9'],
            ], // 0~10% 红轴
          }
        },
        pointer:{   //仪表盘指针
          show:false,
        },
        axisTick: {
          show:false,
        },
        splitLine: {
          show:false,
        },
        axisLabel: {
          show:false,
        },
        title: {
            show: false,
        },
        detail: {
            show: false,
        },
        data: []
      }
    ]
};

之后传入ehcarts组件，渲染echarts

chartInstance.value.setOption(priceZHOption.value, true); 
chartInstance.value.resize();

例如传入的金额分别为 7212289500、20681534。
