[Lens] Tooltip customization basics (hover mode & visibility)

[ghudgins]

Describe the feature:
Elastic-charts supports "Tooltip types". Include additional controls in Lens that expose...

• disabling tooltip
• changing mouse over behavior from "follow" mode to other modes

see "other" tab under "Knobs" here https://elastic.github.io/elastic-charts/?path=/story/grids--lines

Describe a specific use case for the feature:
Other hover types
When visualizing dense data
I need to enable vertical / crosshair tooltip hover axis references
So I can see exactly where on each axis the cursor is as I hover

Disabling
When I want the visualization to appear static
I need to disable the tooltip
So I can present the vis and data as is without interactivity

Nice! I think this option (or set of options) would fit nicely in the Lens toolbar above the chart (adjacent to the visual, legend, and axis options).

Yeah, organization and naming of these options in the Elastic charts docs is interesting. I find it a bit confusing to have what I'd consider two separate options (tooltip visibility and crosshair type) lumped into a single setting. It took me a few seconds to understand on first use.

My first instinct for a Lens implementation would be to have a "Show tooltip" boolean switch (either on or off). If turned on, subsequent controls would be shown below to select a "Crosshair type" (with options to select vertical, horizontal, both, or none).

similar request here - https://discuss.elastic.co/t/kibana-lens/277807 - "show focused values" (instead of all values) from TSVB. likely need a separate issue to track showing only focused value. good one to review for any tooltip design updates as well

Disabling the tootlip is something that is possible in aggBased visualization so I agree about adding this as a setting in Lens. About adding more tooltip modes I am not sure, @markov00 @gvnmagni wdyt?

[markov00]

Adding the ability to visualize just the element hovered (aka Follow) or hide the tooltip on a chart is fine.
Probably I see the hiding more of a dashboard feature (for a read-only mode) than a per-chart configuration.
IMHO this is also a stylistic choice done when everything is implemented in the dashboard, at that level, you start working on perfecting the interaction modes, but this is again a minor request, and the cases described by Graham are actually making of context (I can't really figure it out when I will want a static visualization, how could I understood that the visualization is static and for what reason).

In order to provide better transparency of priorities, issues that will not be prioritized within the next 24 months are being closed.
