The widest canvas: What Streamlit’s Plotly Chart Warnings Really Mean

Using width="content" in st.plotly_chart once silenced a deprecation warning - but now, Streamlit’s latest change brings back a caution. While passing width directly avoids the old keyword error, it triggers a subtle deprecation alert when used. This isn’t a bug, but a needed shift: width=... replaces the outdated width_ or width kwargs, aligning with modern Plotting best practices.

But here’s the catch: legacy code relying on kwargs for layout tuning now faces warnings. The core truth? Plotly’s configurations are evolving toward explicit, direct parameters - not flexible, ambiguous keyword hacks. Even with width, Streamlit warns you: use width instead of **kwargs for control.

This isn’t just a technical tweak - it’s a signal. Streamlit is tightening its API to reduce confusion and future-proof rendering. Using width explicitly ensures compatibility, clarity, and compliance with upcoming changes.

So when you see that warning, don’t ignore it: switch from width="content" with **kwargs to a clean width=500 or height=360. Your charts will render sharper - and your code, future-proof.

Are you ready to simplify your layout - and your stress?
