Add multiple vertical rectangles to a chart in plotly?

[snippsat]

I guess something like this is whant you want.

import pandas as pd
import plotly.graph_objects as go

history = pd.read_csv("sample_data.csv")
history["Date"] = pd.to_datetime(history["Date"], format="%Y-%m-%d")
history.set_index("Date", inplace=True)
recession_dates = history.loc[history["Regime"] == "Recession"].index
normal_dates = history.loc[history["Regime"] == "Normal"].index
fig = go.Figure()
fig.add_trace(go.Scatter(x=history.index, y=history["DJI"], mode="lines"))

# Add vertical rectangles for recession periods
for start_date, end_date in zip(recession_dates[:-1], recession_dates[1:]):
    fig.add_vrect(
        x0=start_date,
        x1=end_date,
        fillcolor="red",
        opacity=0.2,
        layer="below",
        line_width=0,
    )

# Add vertical rectangles for normal periods
for start_date, end_date in zip(normal_dates[:-1], normal_dates[1:]):
    fig.add_vrect(
        x0=start_date,
        x1=end_date,
        fillcolor="green",
        opacity=0.2,
        layer="below",
        line_width=0,
    )

# Adjust plot size
fig.update_layout(
    autosize=False,
    width=1400,
    height=800,
)

fig.show()
