Plotly Shapes - horizontal Rectangle Shapes

📊 Plotly Python
1

Below i can code for two vertical rectangle shapes.
How it should be modified in order to get a two horizontal rectangle shapes.
I have tried my best, but i can’t figure it out.

import plotly.graph_objects as go

fig = go.Figure()

Add scatter trace for line

fig.add_trace(go.Scatter(
x=[“2015-02-01”, “2015-02-02”, “2015-02-03”, “2015-02-04”, “2015-02-05”,
“2015-02-06”, “2015-02-07”, “2015-02-08”, “2015-02-09”, “2015-02-10”,
“2015-02-11”, “2015-02-12”, “2015-02-13”, “2015-02-14”, “2015-02-15”,
“2015-02-16”, “2015-02-17”, “2015-02-18”, “2015-02-19”, “2015-02-20”,
“2015-02-21”, “2015-02-22”, “2015-02-23”, “2015-02-24”, “2015-02-25”,
“2015-02-26”, “2015-02-27”, “2015-02-28”],
y=[-14, -17, -8, -4, -7, -10, -12, -14, -12, -7, -11, -7, -18, -14, -14,
-16, -13, -7, -8, -14, -8, -3, -9, -9, -4, -13, -9, -6],
mode=“lines”,
name=“temperature”
))

Add shape regions

fig.update_layout(
shapes=[
# 1st highlight during Feb 4 - Feb 6
dict(
type=“rect”,
# x-reference is assigned to the x-values
xref=“x”,
# y-reference is assigned to the plot paper [0,1]
yref=“paper”,
x0=“2015-02-04”,
y0=0,
x1=“2015-02-06”,
y1=1,
fillcolor=“LightSalmon”,
opacity=0.5,
layer=“below”,
line_width=0,
),
# 2nd highlight during Feb 20 - Feb 23
dict(
type=“rect”,
xref=“x”,
yref=“paper”,
x0=“2015-02-20”,
y0=0,
x1=“2015-02-22”,
y1=1,
fillcolor=“LightSalmon”,
opacity=0.5,
layer=“below”,
line_width=0,
)
]
)

fig.show()

The shapes with x0, x1 given as strings that represents dates do not work. These strings must be converted to datetime objects. See this example: https://chart-studio.plotly.com/~empet/15269/plotly-shapes-with-date-coordinates-def/#/.
