Tooltip action

Use this action with change({ id: 'Tooltip', context }).

Context

• id?: Get | Update (Update is assumed if omitted)
• visible: true | false
• mode: standard | cards | bubble | external
• showMainTitle: true | false
• mainTitle: Name | Description

Behavior

Tooltip supports:

• Get: returns current tooltip settings in the same shape as Update context.
• Update: applies one or more tooltip fields.

All Update fields are optional.

• visible shows or hides the tooltip.
• mode controls presentation:
  • standard: one shared tooltip
  • cards: one header card per pane
  • bubble: bubble-style tooltip
  • external: disables the built-in tooltip so the host can render tooltip data externally (see CH_TOOLTIPCHANGED).
• showMainTitle toggles the main plot title inside tooltip content.
• mainTitle selects whether that title uses symbol name or symbol description.
