# newline-echarts
    
    ###Introduce
    
    许多人使用百度的echarts.js时候会出现数据名太长覆盖的情况，newline-echarts.js能够很好解决这种换行问题
    
    
    ###Usage
    
    newline(option, 6, 'yAxis')
    * 参数一：是你的option
    * 参数二：是多少个字就换行
    * 参数三：是x轴还是y轴 可选项 'yAxis' OR 'xAxis'
    var chart = echarts.init(document.getElementById("main"));
    <script src="js/echarts.js"></script>
    var option = 
    {
        # your options
    }
    
    option = newline(option, 6, 'yAxis')
    chart.setOption(option)
