highcharts的yAxis标题过长加上这段就行啦

1.  
   labels: {
2.  
   formatter: function() {
3.  
   //获取到刻度值
4.  
   var labelVal = this.value;
5.  
   //实际返回的刻度值
6.  
   var reallyVal = labelVal;
7.  
   //判断刻度值的长度
8.  
   if(labelVal.length > 2) {
9.  
   //截取刻度值
10.  
    reallyVal = labelVal.substr(0, 2) + "<br/>" +labelVal.substring(2, labelVal.length);
11.  
    }
12.  
    return reallyVal;
13.  
    }
14.  
    },
