Automatically adjusting axis range so that marker fits in Plotly

I'm stuck with this silly problem and can't solve it. I need for several graphs to have the same x axis range (because they are shown on top of each other and have timestamp as x axis). My first guess was to simply find the lowest and the highest of x values for all the plots and use them as x axis range for all of them. It kinda works, but now the graphs look bad and the marker doesn't fit (see the picture).

import plotly.graph_objs as go

x1 = [1, 2, 3]
y1 = [1, 2, 1]
x2 = [1, 2]
y2 = [2, 1]
xmin = min(min(x1), min(x2))
xmax = max(max(x1), max(x2))
figure1=go.Figure(
    data=[
        go.Scatter(x=x1,
                   y=y1,
                   marker={'size': 20})
    ],
    layout={'xaxis': {'range': [xmin, xmax]}}
)
figure2=go.Figure(
    data=[
        go.Scatter(x=x2,
                   y=y2,
                   marker={'size': 20})
    ],
    layout={'xaxis': {'range': [xmin, xmax]}}
)
figure1.show()
figure2.show()

Is it possible to automatically adjust axis limits just enough for the marker to fit? Or maybe there is another solution for this task?

Thanks!

BTW, if I could just read what are the axis limits that plotly sets automatically, that would be very helpful

You just need to add

figure1.update_layout(xaxis = dict(range=[0.9, 3.1]))
figure2.update_layout(xaxis = dict(range=[0.9, 2.1]))

before figure1.show() and figure2.show()

Option 1: Adjust xmin and xmax

In many cases you only need to add a little adjustments to your calculated xmin and xmax:

Option 2: adjust padding

You can create more space between the plotting area and the axis lines using the pad argument in go.layout.Margin(). You can adjust the setup further using the l, r, t, b arguments too.

enter image description here

# imports
import plotly.graph_objs as go

x1 = [1, 2, 3]
y1 = [1, 2, 1]
x2 = [1, 2]
y2 = [2, 1]
xmin = min(min(x1), min(x2))
xmax = max(max(x1), max(x2))

xmin_adjust = 0.5
xmax_adjust = 0.5

figure1=go.Figure(
    data=[go.Scatter(x=x1,
                     y=y1,
                    marker={'size': 20})],
    layout={'xaxis': {'range': [xmin-xmin_adjust, xmax+xmax_adjust]},
            'margin':go.layout.Margin(l=50, r=50, b=50, t=50, pad=50)})
            
figure2=go.Figure(
       data=[go.Scatter(x=x2,
                        y=y2,
                        marker={'size': 20})],
    
       layout={'xaxis': {'range': [xmin-xmin_adjust, xmax+xmax_adjust]},
            'margin':go.layout.Margin(l=50, r=50, b=50, t=50, pad=50)})
               
figure1.show()
figure2.show()
