Show xaxis on both sides (Top and bottom)

[akroma]

Hey @smail ,

I read @adamschroeder’s and @jlfsjunior’s answers and tried to create an example.

import pandas as pd
import numpy as np
import plotly.graph_objects as go
from plotly.subplots import make_subplots

data = pd.read_csv("example.dat", sep = "\t")



# SUBPLOT CONFIG
fig = make_subplots(rows=1,
                    cols=3,

                    specs=[[{"type": "scatter"},
                            {"type": "scatter"},
                            {"type": "scatter"}
                            ]
                           ],

                    column_widths=[2.5, 2.5, 2.5],
                    shared_yaxes=True
                    )



# GHOST TRACES TRACE NAMES: ghost1 and ghost2
fig.add_trace(go.Scatter(x=None, y=None, name="ghost1", showlegend=False), row=1, col=1)    #COLUMN 1
fig.add_trace(go.Scatter(x=None, y=None, name="ghost2", showlegend=False), row=1, col=2)    #COLUMN 2

#Since we have 3 subplots
#x-axis ->     xaxis, xaxis2, xaxis3

#When we add additional traces (2 ghost + 1 data)
#New x-axis -> xaxis4, xaxis5, xaxis6


fig.update_layout(xaxis4 = {'anchor': 'y',  'overlaying': 'x', 'side': 'top'})  #Ghost Axis Column1

fig.update_layout(xaxis5 = {'anchor': 'y2', 'overlaying': 'x2', 'side': 'top'}) #Ghost Axis Column2

fig.update_layout(xaxis6 = {'anchor': 'y3', 'overlaying': 'x3', 'side': 'top'}) #Data Axis Column3
    


# ADD TRACES

# ONLY TEMP (FIRST GRAPH)
fig.add_trace(go.Scatter(x=data["temperature"],
                         y=data["depth(m)"]*-1,

                         name="temperature",
                        
                         mode='lines',
                         marker=dict(color="red"),
                       
                         ),
              
              row=1, col=1
              )

# ONLY PRESSURE-(PSIG) (SECOND GRAPH)
fig.add_trace(go.Scatter(x=data["pressure(psig)"],
                         y=data["depth(m)"]*-1,

                         name="pressure(psig)",
                        
                         mode='lines',
                         marker=dict(color="blue"),
                       
                         ),
              
              row=1, col=2
              )


# TEMP + PRESSURE-(PSİG) (THIRD GRAPH)
fig.add_trace(go.Scatter(x=data["pressure(psig)"],
                         y=data["depth(m)"]*-1,

                         name="pressure_temp",
                        
                         mode='lines',
                         marker=dict(color="green"),
                         
                       
                         ),
              
              row=1, col=3
              )

fig.add_trace(go.Scatter(x=data["temperature"],
                         y=data["depth(m)"]*-1,

                         name="temp_pressure",
                        
                         mode='lines',
                         marker=dict(color="purple"),
                       
                         ),
              
              row=1, col=3
              )



# UPDATE AXİS

#Ghost Traces (Column 1 and 2)
fig.update_traces(xaxis='x4',yaxis='y',   selector = ({'name':'ghost1'}))
fig.update_traces(xaxis='x5',yaxis='y2', selector = ({'name':'ghost2'}))

#Set Range
fig.update_layout(xaxis4_range=[data["temperature"].min(),data["temperature"].max()])
fig.update_layout(xaxis5_range=[data["pressure(psig)"].min(),data["pressure(psig)"].max()])


#Real Data (Column 3)
fig.update_traces(xaxis='x3',yaxis='y3', selector = ({'name':'pressure_temp'}))
fig.update_traces(xaxis='x6',yaxis='y3', selector = ({'name':'temp_pressure'}))

print(fig.layout)

fig.show()
