How to plot a scatter plot and line plot in one figure and setting a column as the color?

Ahh, you have to convert True/False to a numerical value like so: import plotly.express as px import pandas as pd import random # create data days=7 timespan = pd.date_range('01/01/2022', periods=days, freq='D') value = [np.random.randint(1,50) for _ in range(days)] color = [np.random.randint(1,50) for _ in range(days)] value2 = [[True, False][np.random.randint(0,2)] for _ in range(days)] value2 = [1 if val else 0 for val in value2] # create figure fig = px.scatter(x=timespan, y=value, color=…
