Inside Jmtbwqmac Ukysho Plotly_chart Kwargs Deprecation

Dxkjhfz jqkxfucqe When Streamlit phased out deprecated width=content for st.plotly_chart, many developers assumed the kwargs shortcut would remain safe. But recent changes now warn: “Variable keyword arguments for width are deprecated - use config instead.” This shift isn’t a bug, but a regression: what once worked silently now triggers warnings.

Here is the deal: dropping width=content triggers a warning even when you pass width="content". The fix? Use config to control layout, not raw kwargs.

The core issue lies in how Streamlit handles legacy config syntax. Using kwargs with width=content was a quick patch - but docs now clarify it’s deprecated. Misusing it risks confusing users and breaking consistency.

Today, the bottom line: trust config over kwargs for plot layout. It’s cleaner, safer, and future-proof.

The Bottom Line: Stop relying on kwargs for width. Use config to avoid warnings and keep your Streamlit apps aligned with evolving best practices.
