Idea: clarify densityplot helper naming for readability

[sanjiti-gill]

Hi ArviZ maintainers 👋,

I’ve been slowly exploring the Matplotlib density plotting code while getting familiar with the codebase.

While reading arviz/plots/backends/matplotlib/densityplot.py, I noticed the internal helper function _d_helper. From its parameters, it seems to primarily handle styling- and presentation-related logic for density plots.

I was wondering whether renaming this helper to something more descriptive (for example, indicating its role in preparing/applying density plot styles) could improve readability and make the plotting flow easier to follow for new contributors.

This is just an observation from a beginner’s perspective — I’d love to hear your thoughts or guidance on whether this aligns with current refactoring plans.

Thanks for maintaining ArviZ!

Hi, all the functionality in densityplot.py has already been refactored. I am about to merge #2494 which will delete all that. If you are interested in contributing things related to plotting you should take a look at https://github.com/arviz-devs/arviz-plots. If you are interested in general in helping with the refactor, also check out https://github.com/arviz-devs/arviz-base and https://github.com/arviz-devs/arviz-stats

Thank you for the clarification!
I’ll take a look at arviz-plots and explore ways to contribute there, especially around plotting.
I’m also interested in understanding the ongoing refactor and will review arviz-base and arviz-stats as suggested.
Thanks again for pointing me in the right direction.
