Mixed Subplots in Python

How to make mixed subplots in Python with Plotly.

New to Plotly?

Plotly's Python library is free and open source! Get started by downloading the client and reading the primer.
You can set up Plotly to work in online or offline mode, or in jupyter notebooks.
We also have a quick-reference cheatsheet (new!) to help you get started!

Version Check

Note: Subplots with multiple chart types (i.e. cartesian and 3D) are available in version 1.12.11+
Run pip install plotly --upgrade to update your Plotly version
