Display hover text on top instead of to the right

Hover labels in Plotly are displayed on the right hand side of the displayed object, for example:

This makes the numbers misaligned, especially for e.g. bar charts, where you'd expect a label to be shown on top of the bar instead of to the right of the bar

Is there an option to make the labels appear on top instead? In my second example it would appear in the same position as my current annotations — right on top of the bar. In the first example it should appear on top of the bubble.

该 issue 未指定任何文件、测试或入口点。首先定位柱状图和气泡图的悬停标签渲染逻辑，然后比较所附的两个示例；当某个选项能将悬停标签放置在所显示对象的上方而不是右侧时，即视为完成。
