Google Charts LineChart选项不完全正常工作（双y轴）

我在D3中构建了几个图表但是在客户要求我开始使用谷歌图表 . 到目前为止，我非常喜欢它，但我无法让选项正常工作 .

我正在使用angular-google-chart并且我仔细检查了选项是否正确传递给谷歌api，他们是 . 我也彻底阅读了line chart docs，所以我非常有信心语法是正确的，但是如果您发现以下数据存在任何问题，请告诉我 .

有几个选项不起作用，但特别是，没有一个vAxis选项正常工作;其中最重要的是y轴 Headers 没有显示 .

我注意到线图api有点挑剔 . 例如，我使整个图表 Headers 更大，它只是随机停止显示顶部图例，所以我不得不改回来 . 我希望有一些文件概述了每个选项变更的权衡 .

请注意，我试图显示两个y轴 .
