Hover Text and Formatting in Python
How to use hover text and formatting 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¶
Plotly's python package is updated frequently. Run pip install plotly --upgrade to use the latest version.
