Zz1Change opened a new issue #8210: 设置X轴最小值后,折线图最后一个数据回连(数据已正确排序)
URL: https://github.com/apache/incubator-echarts/issues/8210

为了方便我们能够复现和修复 bug，请遵从下面的规范描述您的问题。
-->
### One-line summary [问题简述]
1.动态折线图,dataset数据为动态,设置了connectNulls=true.
初始X轴(time)最大最小值为默认的空,数据导入set option后正常
随着时间的过去,会在某一刻,删掉一些前面的数据 然后set option设置X轴的最小值,
在设置完后,图表末尾几个点就错乱,具体表现为最后一个点往回连到倒数第四个点
检查过dataset数据的X轴时间排序没问题.
又过了一阵子,再到下一跳新数据set进去,图表又正常了.
请问如何解决?
设置了X轴最小值后有没有相应操作能让图表强制刷新一下?
2.设置了yAxis.scale=true,但是当数据为0的时候,直线不在垂直方向的中央,而是贴在最底下0,感觉像是默认
不显示负数范围一样
### Version & Environment [版本及环境]
+ ECharts version [ECharts 版本]:4.0.4
+ Browser version [浏览器类型和版本]:firefox59.0.1
+ OS Version [操作系统类型和版本]:win 10
### Expected behaviour [期望结果]
1.设置X轴最小值后,图表折线不再发生错乱(最后一个点往回连线)
2.数据不好的时候(全为0)的一条直线,显示在图表垂直居中,而不是现在贴在最底下0
