相同的数据，Echarts图表绘制的有效数据点数明显比AmCharts少得多，容易造成该时间点数据为0的误解，影响图标数据的可读性。。。。
这个问题影响度还是比较广的，麻烦尽快解决下，客户对数据要求很高，不能有太多偏差

同样一组一模一样的数据，amcharts跟Echarts绘制出来的精度差别有点大，有些重要点被过滤掉了，严重影响数据可视化。。。希望能尽快得到支持，客户对数据要求蛮严格的。。。

嗯，我们接下去会对数据抽希算法做调整。

能否有个大概的时间点哈？我们系统3月底就要上线对外开给客户，客户量比较多，比较紧急哦，希望你们能把这个优先级调高哈~

line 添加配置项 dataFilter，支持 'min', 'max', 'average', 'nearst' 选项，默认为 'nearest'。除了这四个默认的 filter 也可以是自定义函数。
