Echarts改变Y轴坐标的数据

option

option = {
        tooltip: {
            trigger: 'axis'
        },
        legend: {
            data:['车流量','人流量']
        },
        toolbox: {
            show: true,

        },
        xAxis:  {
            type: 'category',
            boundaryGap: false,
            data: ["08:00","09:00","10:00","11:00","12:00","13:00","14:00","15:00","16:00","17:00","18:00","19:00","20:00"]
        },
        yAxis: {
            type: 'value',
            axisLabel: {
                 formatter: function(v){
                     return  tranNumber(v);
                 }
            }
        },
        series: [
            {
                name:'车流量',
                type:'line',
                data:[0,0,10000,3000,30000,30000,30000,30000,30000,30000,30000,30000,30000],
               
            },
            {
                name:'人流量',
                type:'line',
                data:[153,4000,4000,15000,4000,4000,4000,4000,4000,4000,4000,4000],
                
            }
        ]
    
};

主要:

yAxis: {
            type: 'value',
            axisLabel: {
                 formatter: function(v){
                     return  tranNumber(v);
                 }
            }
        }

tranNumber()方法

function tranNumber(num){
    var numStr = num.toString();
    // 十万以内直接返回
    if (numStr.length <5 ) {
        return numStr;
    }
    //大于8位数是亿
    else if (numStr.length > 8) {
        var decimal = numStr.substring(numStr.length - 8, numStr.length - 8 );
        return parseFloat(parseInt(num / 100000000) + '.' + decimal) + '亿';
    }
    //大于6位数是十万 (以10W分割 10W以下全部显示)
    else if (numStr.length > 5) {
        var decimal = numStr.substring(numStr.length - 4, numStr.length - 4)
        return parseFloat(parseInt(num / 10000) + '.' + decimal) + '万';
    }else if(numStr.length == 5){
        var decimal = numStr.substring(numStr.length - 3, numStr.length - 4)
        return parseFloat(parseInt(num / 10000) + '.' + decimal) + '万';
 
        
    }
   
};
