Plotly Express Gallery

Plotly Express is a terse, consistent, high-level wrapper around Plotly.py for rapid data exploration and figure generation.

This notebook demonstrates various plotly_express features. Reference documentation and a step by step walkthrough notebook are also available.

You can also read our Medium announcement article for more information on this library.

A single import

import plotly_express as px

Built-in sample datasets

print(px.data.iris.__doc__)
iris = px.data.iris()
tips = px.data.tips()
gapminder = px.data.gapminder()
election = px.data.election()
wind = px.data.wind()
carshare = px.data.carshare()

Scatter and Line plots

px.scatter(iris, x="sepal_width", y="sepal_length")
px.scatter(iris, x="sepal_width", y="sepal_length", color="species")
px.scatter(iris, x="sepal_width", y="sepal_length", color="species", marginal_y="rug", marginal_x="histogram")
px.scatter(iris, x="sepal_width", y="sepal_length", color="species", marginal_y="violin",
           marginal_x="box", trendline="ols")
iris["e"] = iris["sepal_width"]/100
px.scatter(iris, x="sepal_width", y="sepal_length", color="species", error_x="e", error_y="e")
