One-line summary [问题简述]

中文简述：
最近在echarts官网上发现了一个问题，关系日历图的系列数据不能取到盖图表的最后一天，并且它的时间戳不是有正规的日历转换过来的话会有报错。按着常理来说不管用户写的数据正确与否，一般只是显示与不显示问题，而不应该报错。如果有人能解决这一问题，并且告诉我，我十分感谢！

English brief:：
Recently discovered a problem in echarts official website, the relationship between calendar figure series data cannot take to cover the chart at the end of the day, and its time stamp is not have formal calendar conversion to come over there will be an error.According to common sense, whether the data written by the user is correct or not, it is generally only showing and not displaying the problem, and should not be reported wrong.If anyone can solve this problem and tell me, I am very grateful!
