雷达图中的数据数组中第一项是“-”时显示错误

[katherinebai]

One-line summary [问题简述]

雷达图中的数据是 ["-", 5, 8, 1, 4]，其中“-”处于第一位和中间位置时表现不一致，当“-”处于数组第一位时，tooltip消失后连线消失了；当“-”处于其他项时表现正确。

Version & Environment [版本及环境]

• v4.1.0 [ECharts 版本]:
• Chrome [浏览器类型和版本]:
• Win8.1 [操作系统类型和版本]:

Expected behaviour [期望结果]

当雷达图中系列的数据是'-'时，相邻的两个点可以连线，而且当‘-’处于数组中的第一位时，将鼠标放置到某个点时tooltip消失后连线不消失。
