如何消除 plotly.express.timeline 中连续日期和相邻日期之间的差距？

Question

In my Python script I gather the datetime objects for two time periods via dateutil.parser like so:

from dateutil import parser

start_date_1 = parser.parse("2010-08-01").date()
end_date_1 = parser.parse("2010-11-05").date()
start_date_2 = parser.parse("2010-11-06").date()
end_date_2 = parser.parse("2010-11-12").date()

When trying to visualize these time periods with plotly.express.timeline , there is a gap between consecutive and directly adjacent dates (2010-11-05 and 2010-11-06). Is there any way to join these two bars without overlapping the dates?

df = pd.DataFrame([
        dict(Task="period_1", Start=start_date_1, Finish=end_date_1, Stack="stack_2"),
        dict(Task="period_2", Start=start_date_2, Finish=end_date_2, Stack="stack_2"),
    ])
    
fig = px.timeline(df,
                x_start="Start",
                x_end="Finish",
                y="Stack",
                color="Task",
                hover_name="Task",
                opacity=.7,
                width=1000)

    fig.update_traces(marker_line_width=1.0, opacity=0.95)

    fig.update_layout(
        barmode="overlay",
        xaxis = dict(
            automargin=True,
            dtick="M1",
            tickformat="%Y-%m-%d",
            type="date",
            showgrid=True,
            rangeslider_visible=True),
        
        yaxis = dict(
            automargin=True,
            visible=False,
            autorange="reversed",
            showgrid=True),
        
        legend=dict(
        title=""))

When giving a daterange to plotly, the second index will be exclusive. (ie You are creating a bar up to 2010-11-05 but not including it. To fix this, add 1 day to each of you endpoints.

start_date_1 = parser.parse("2010-08-01").date()
end_date_1 = parser.parse("2010-11-06").date()
start_date_2 = parser.parse("2010-11-06").date()
end_date_2 = parser.parse("2010-11-13").date()
