封装echarts成vue component EChartsLineComponent

封装说明

为了减少一些公共代码和方便使用echarts的line图形，有限制条件的封装echats中的line类型的图，该Component名称为EChartsLineComponent。

重写重点

1. 以dateset属性中的source来判断图形是否包含数据，意味着需要通过dataset，source的方式配置数据。初始化option是要定义datasource，source属性，否则不能正常使用该EChartsLineComponent。

   option:{dataset: {// 第一行为表头，第一个元素为X轴，其后为Y轴元素// 第二行为具体数据点source: []}
   }
   

   同时，在定义的option中需要先确认数据每条线显示的效果，即配置series属性。

   option:{series: [{type: 'line',smooth: true,},{type: 'line',smooth: true,}]
   }
   

2. 定义了空数据的展示效果，舍弃了有数据状态下的grid属性。
   

3. 增加了窗口自适应写法，并确定初始化图标高度为400px，宽度100%。
