make all subplots display data when hovering instead of just current subplot

【中文】
我希望 当hover在某一位置，所有子图对应的数值信息都显示出来，而不是只有当前的子图显示。

• 所有子图已经共享x轴
• 已经设置hovermode='x unified',

【Question】
I hope that when hovering over a specific position, all subplots display the corresponding value information, instead of only the current subplot.

• All subplots share the x-axis.
• hovermode='x unified' is already set.

self.figer = make_subplots(rows=nrows, cols=ncols, shared_xaxes=True,specs=specs, vertical_spacing=0.05 ) # 画布的figer
self.figer.update_layout(
# xaxis_rangeslider_visible=True,
hovermode='x unified',
spikedistance=-1
)
效果还是不行

Start with the make_subplots call using shared_xaxes=True and the subsequent update_layout settings with hovermode='x unified' and spikedistance=-1. Reproduce the behavior with a minimal multi-subplot example, then verify that hovering at one x position displays the corresponding values from every subplot.
