Share all x-axes of a subplot (rows and columns)

Question

I try to share all x-axes of a subplot structure with several columns, but I can’t get the solution. With ‘share_xaxes=True’ only the x-axes of the same row are linked, and I am not able to change the ‘xaxis’ paramater from the figures in the subplot. Any idea?

In the Plotly documentation you can see that the axes have an attribute called scaleanchor (see https://plot.ly/python/reference/#layout-xaxis-scaleanchor). You can use it to connect as many axes as you like. I tested it out on a simple subplot with 2 rows and 2 columns where all x-axes are connected:

import plotly.plotly as py
import plotly.graph_objs as go

# -*- coding: utf-8 -*-
import dash
import dash_core_components as dcc
import dash_html_components as html

external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']

app = dash.Dash(__name__, external_stylesheets=external_stylesheets)


def create_figure():
    trace1 = go.Scatter(
        x=[1, 2, 3],
        y=[2, 3, 4]
    )
    trace2 = go.Scatter(
        x=[1, 2, 3],
        y=[5, 5, 5],
        xaxis='x2',
        yaxis='y2'
    )
    trace3 = go.Scatter(
        x=[1, 2, 3],
        y=[600, 700, 800],
        xaxis='x3',
        yaxis='y3'
    )
    trace4 = go.Scatter(
        x=[1, 2, 3],
        y=[7000, 8000, 9000],
        xaxis='x4',
        yaxis='y4'
    )
    data = [trace1, trace2, trace3, trace4]
    layout = go.Layout(
        xaxis=dict(
            domain=[0, 0.45],
            anchor='y'
        ),
        xaxis2=dict(
            domain=[0.55, 1],
            anchor='y2',
            scaleanchor='x'
        ),
        xaxis3=dict(
            domain=[0, 0.45],
            anchor='y3',
            scaleanchor='x'
        ),
        xaxis4=dict(

            anchor='x'

    )

    return fig


app.layout = html.Div(children=[
    html.H1(children='Hello Dash'),

    html.Div(children='''

    )
])

I know this post is old, but maybe this can help someone else:

Just use the option shared_xaxes = 'all' when you create subplots with make_subplots() and all x-axes will be shared.
