Is it possible making spike lines in several subplots having 2 columns?

I’m making a graph with 3 rows and 2 columns. (refer to below figure)

Is there any method applying vertical spike line sharing x-axis in all subplots?
(all subplots share the x-axis.)

Hi @kormo09 and welcome to the community!

Have you looked through the solutions/discussion from the below threads with a similar topic?

Can't draw spike line across subplots with make_subplots in 4.0.0

After upgrading to plotly 4.0.0, I can't see how to create a spike line across s…hared axes created with make_subplots. Previously I was using code like this: ```python from plotly.tools import make_subplots from plotly.io import write_html fig = make_subplots(rows=4, cols=1, shared_xaxes=True) x_vals = list(range(10)) y_vals = [x**2 for x in x_vals] fig.add_scatter(x=x_vals, y=y_vals, row=1, col=1) fig.add_scatter(x=x_vals, y=y_vals, row=2, col=1) fig.add_scatter(x=x_vals, y=y_vals, row=3, col=1) fig.add_scatter(x=x_vals, y=y_vals, row=4, col=1) fig.update_xaxes(spikemode='across+marker') write_html(fig, 'out.html', auto_open=True) ``` The resulting figure showed spike lines across axes because only one x axis was created: ![image](https://user-images.githubusercontent.com/12515343/61720630-6ccb2480-ad67-11e9-8757-d4093d55d633.png) But in 4.0, multiple x axes are created so the spike line no longer draws across all subplots: ![image](https://user-images.githubusercontent.com/12515343/61720563-4f965600-ad67-11e9-8709-c69a77d3daf1.png) Is there any way around this? Thanks!

Thank you for your kind reply.
But the links in your answer correspond to multiple plots with only 1 column.
My question is about more than 2 columns.
