处理后

axisLabel配置

 axisLabel: {
            interval: 0,
            formatter: function (value) {
              return spliceStr(value, 4)
            },
            textStyle: {
              fontFamily: 'Microsoft YaHei',
              color: 'rgba(170, 185, 208, 1)',
              fontSize: 12
            }
          },

截取方法 只截取中文

var spliceStr = function (value, len) {
    if (value.length <= len) {
        return value
    }
    
    var newValue = "";
    var k = 0;
    for (var i = Math.ceil(value.length / len); i > 0; i--) {
       
        newValue += value.substr(k, len) + (i == 1? '':'\n');
        k += len;
        
    }
    return newValue;
}
