Greetings,
I am able to call fig.update_layout(hovermode="x unified") to have a vertical (or horizontal with x unified) line when my mouse hovers my chart like this:

I know Plotly can draw both “x unified” and “y unified” together so that I can get a crosshair on my chart. How can I have a crosshair on my chart with Plotly Python?
Thank you,
