So I have this data series that has a binary recession variable and I would like to create rectangular highlights, just like these: https://plot.ly/python/shapes/#highlighting-time-series-regions-with-rectangle-shapes. I am new to plotly and cannot figure out how to do this. Any tipps would be much appreciated. Thank you.
Hi @fkpisk welcome to the forum! What exactly can’t you adapt from the linked example to your use case?
More generally, if you are new to plotly I recommend reading through the following doc pages
and to take a quick look at https://plot.ly/python/plotly-fundamentals/ and https://plot.ly/python/#basic-charts
For an automatic creation of rectangular shapes to highlight some time-intervals on the graph, you can define a function that returns the filled rectangle, instead of defining explicitly each shape, as in the example at the link you pasted here:
import plotly.graph_objects as go import pandas as pd def get_highliting_rectangle(start_date, end_date, fillcolor='blue', opacity=0.25): return dict( type="rect", xref="x", yref="paper", x0=start_date, y0=0, x1=end_date, y1=1, fillcolor=fillcolor, opacity=opacity, layer="below", line_width=0, ) df = pd.read_csv('https://raw.githubusercontent.com/plotly/datasets/master/finance-charts-apple.csv') fig = go.Figure([go.Scatter(x=df['Date'], y=df['AAPL.High'])]) shapes =  shapes.append(get_highliting_rectangle("2015-06-25", "2015-08-03")) shapes.append(get_highliting_rectangle("2016-01-08", "2016-02-24")) fig.update_layout(shapes=shapes, width=700, height=450)
