Python – Timeline chart

May 31, 2023

Does anyone know if it’s possible to create a graph like this, with some Python library? If so, does anyone have any examples to share?

Thanks.

>Solution :

It should be pretty straight forward using plotly.express.timeline. Look at the first example on that page. If you want it on one y-axis position like your screenshot then try

# example directly from Plotly
import plotly.express as px
import pandas as pd

df = pd.DataFrame([
    dict(Task="Job A", Start='2009-01-01', Finish='2009-01-03'),
    dict(Task="Job B", Start='2009-01-03', Finish='2009-01-16'),
    dict(Task="Job C", Start='2009-01-16', Finish='2009-01-18')
])
# add color param and remove the y param from the example
fig = px.timeline(df, x_start="Start", x_end="Finish", color='Task')
fig.show()
