【问题描述】：
我正在尝试使用 Highcharts 创建带有日期时间 x 轴和 y 轴的热图。
除了 y 轴对齐之外，一切看起来都不错。
“00:00”应该在图表的最底部，但它偏移/居中于第一个框。
我环顾四周，但无法确定需要调整哪些设置。任何帮助表示赞赏。
请看下面我的 jsFiddle 示例。数据数组包含[EpochTicksForStartOfDay, TicksForTimeOfDay, Value]
https://jsfiddle.net/h2zb2tos/5/
更新：我希望 y 轴线和标签与热图框的底部对齐。第一个（最低的）盒子在 00:00 “开始”，第二个在 01:00，第三个在 02:00 等等。所以我希望这些线路排成一行。

如果您将所有数据点的值增加一半，那么所有点都将位于网格线上并与刻度对齐 - jsfiddle.net/h2zb2tos/6 这是您想要得到的吗？
