[facorread]

@inconspicuous99 This PR failed both checks; the project has implemented new checks since.

Would you like to propose an updated PR and some tests? The project would appreciate it.

Seems we already have merged a PR that fix the bug that candlestick element discard the filled field from the style.

See b41b5a7

Plus this change just make the Candlestick::new doesn't compatible with previous version, thus it's a breaking change. So I am prefer the fix I linked above.

Thanks for your contribution and please don't mind I close the PR.
