hovermode + spikemode all the time

Hi,

looking for a solution to a chart that I'm doing I got to this link:
https://github.com/plotly/plotly.js/issues/1959

basically, what I want is to display a label at the end of a spikeline instead of the marker (little circle) but also what I want and what was requested on the link above, was to have a way to always have the spike line and display it so the user doesnt have to go to the closes point in order to see the spike line.

here is an image of what I want to achieve:

the lines in the X axis is always there and also it show a label at the end (grey label, not the red one)

先阅读链接的 plotly.js issue #1959，以及本 issue 对 hovermode 和 spikemode 行为的描述。将所请求的始终可见的 X 轴 spike 线和末端标签与附带的截图进行比较，然后确定预期的交互方式和验收标准，再定位相关的图表行为。
