Value labels on stacked bar chart now show 0.0 regardless of the actual value

[rea725]

Bug description

This is observed in version 5.0.0. It was not an issue in 3.x. Not sure about 4.x.

The value label in the stacked bar chart is always showing 0.0, and not the actual stacked bar value.

Hey @rea725! 👋 I'm here to help you with any bugs, questions, or contributions you have for the project. Let's squash those bugs together!

The issue with value labels on a stacked bar chart showing 0.0 instead of the actual values in Superset version 5.0.0 could be related to the getNumberFormatter function not being correctly configured or returning a formatter that defaults to 0.0. The drawBarValues function uses this formatter to display the values on the chart. If getNumberFormatter(axisFormat) is not returning the correct formatter, it could lead to the labels displaying 0.0. You may need to check the configuration or implementation of getNumberFormatter to ensure it is set up to format the numbers correctly based on the axisFormat provided ^[1].

[just a thought] - it'd be great to have a way to reproduce issues in ephemeral environments. On PRs it's easy to get an ephemeral environment created, and from there, you could create a new chart on top of the existing datasets that shows the issues, allowing for devs to start from a clear repro. Would even be easy to export-from-eph-env and import in local dev environment. Anyhow, not related to your issue, but thinking of ways to make people more productive on the repo.

This would require tweaking the eph env GHA to be triggered in issues, ideally could take in a SHA parameter as to what to build.

In any case, clearly looks like a bug that needs to be addressed.

Looks like it might be addressed already in #32337 if you're using a stacked bar scenario.
