Laravel-Admin-Panel: PHP’s Hidden Deprecation in Plotly Charts

When Plotly’s st.plotly_chart introduced the width="content" parameter, users expected seamless rendering - yet a subtle trap lurks beneath the surface. Despite passing width="content" with no explicit kwargs, a deprecation warning now fires, warning that variable keyword arguments are obsolete. This is no minor detail - recent tests on Streamlit 1.50.0 confirm the warning appears even when no kwargs are used.

This behavior reveals a deeper friction in how legacy setups interpret parameter defaults. Developers once relied on flexible kwargs to fine-tune Plotly’s rendering, assuming full control. But now, the framework shifts responsibility to the config option, silently phasing out old patterns without clear migration paths.

The hidden cost? Mixing width="content" with **kwargs triggers a warning - exactly the opposite of what many expect. For teams building dashboards with Laravel-Admin-Panel, this is more than a technical hiccup: it’s a reminder to audit configuration code for deprecated practices.

The bottom line: Always verify how Plotly integration handles parameters. Use fig.update_layout(width="content") without **kwargs to avoid warnings. And when in doubt, consult the latest docs - because the shift from kwargs to config isn’t just semantic; it’s a real change in how the system communicates. Does your chart behave as expected? Check your config, not just your code.
