我有一个多系列（时间）折线图。我在单个系列上定义了十字线-x绘图区域指南标签。如果一个系列具有多个数据元素（点），则该系列中所有点的绘图区域指南标签显示正常。如果一个系列只有一个点，特定系列无法显示绘图区域指南标签。我使用的是最新的Chrome浏览器（63.0.3239.132）
我在错误图表中包含了下面的配置，但是在codepen上也设置了2个示例。
示例中没有显示1点系列的指南标签 https://codepen.io/iklotzko/pen/QQqEmp
显示两个系列的指南标签的示例 https://codepen.io/iklotzko/pen/bLoeqp
上述示例之间的唯一区别是错误示例中的S2只有1分。
错误示例的配置 系列1（S1）有2个点，2个系列（S2）有1个点。 S2的引导标签无法在绘图区域中显示。

我通过电子邮件发送了ZingChart，他们证实这是2.6.3中的一个错误，他们修复了这个错误并将在下一个版本中提供，大概是2.6.4或2.7.0
