A collection of tasks and issues related to the introduction of the new multi-layer time axis in Kibana.

Tasks

• Remove specified locale translations for multi-layer time axis #2158

• [xy] Connect multi-time axis to Kibana Locale #2157

• Improve gridline styles (nicely mark major, minor and ticks)

• testing: addition of VRT cases for the various time resolutions (quite a few zoom levels from ms to decades, not all covered yet)

• testing: addition of tests on time zones get handled correctly

• Lens: try handling the clustered bar time series within the library, or switch to ordinal bar chart within Lens in that specific case

• [Lens] Connect Kibana Locale to Elastic-Charts kibana#166240

• Verify and fix darkmode (fix(xy): time axis improvements #1445)

• Don't show tick/grid line for leftmost tick if it's outside the domain (fix(xy): multilayer time axis tick/grid only when tick is inside domain #1446)

• Show tick value in label, rather than start of the domain for a leftmost tick outside the domain (fix(xy): multilayer time axis tick/grid only when tick is inside domain #1446)

• Align font sizes in axes ([charts] Fix multilayer time axis styles kibana#116749)

• DRY multi-layer time axis style in Kibana (move the style in charts plugin and import when needed) ([charts] Fix multilayer time axis styles kibana#116749)

• TSVB: Disable multi-time axis when the chart is configured with clustered bars ([charts] Fix multilayer time axis styles kibana#116749)

• Lens: Hide Disable axis tick label orientation configuration when using the multilayer axis with tooltip: "Axis orientation is not compatible with time axis"

• Visualize: align, filter and truncate can be removed disabled from the UI when using the multiLayerTimeAxis with tooltip "{Featurename} is not compatible with time axis"

• UX issue: sparser ticks/gridlines 2: chart width dependent minimum allowed tick pixel distance

• UX issue: theme integration and ensuring layer and theme dependent tick lengths (or lack thereof), such as grid saliency

• AM/PM --> 24h
