Protected ReadonlymovableProtected ReadonlyhighlightProtectedhighlightGets the current state of the trace including audio, braille, text, and highlight information.
The current TraceState
ProtectedoutProtectedhighlightProtectedautoplayProtectedhasProtectedvaluesProtectedaudioProtectedbrailleProtectedtextProtecteddimensionProtectedgetGets safe row and column indices to prevent accessing undefined values
Object with safe row and column indices
Registers an observer to receive state updates.
The observer to add
Removes an observer from receiving state updates.
The observer to remove
Notifies all registered observers with the current state.
Notifies observers that an out-of-bounds condition occurred.
Utility function to compare point values for rotor functionality
boolean value
Get all highlight SVG elements for this trace Used by HighlightService for high contrast mode
Array of all SVG elements, or empty array if none
Get all original (visible) SVG elements for this trace. These are the actual rendered elements, not the hidden clones used for highlighting. Used by HighlightService for high contrast mode color changes.
Array of all original SVG elements, or empty array if none
ProtectedgetResets the trace to initial entry state
Get available extrema targets for the current navigation context
Array of extrema targets that can be navigated to Default implementation returns empty array (no extrema support)
Base implementation for navigateToExtrema Subclasses must override to provide actual implementation
The extrema target to navigate to
ProtectedfinalizeCommon post-navigation cleanup that should be called by subclasses after they update their internal state
ProtectedupdateDefault implementation for updating visual point position Subclasses can override if they need custom positioning logic
Checks if this plot supports extrema navigation.
True if extrema navigation is supported
Base implementation for getting current X value Subclasses can override if they have different data structures
Moves to a specific X value in the trace.
The X value to navigate to
True if the move was successful, false otherwise
Gets the unique identifier for this trace.
The trace ID
Checks if the specified coordinates are within bounds of the element.
The x-coordinate
The y-coordinate
Object containing the SVG element and its position
The SVG element to check bounds against
The row position of the element
The column position of the element
True if the point is in bounds, false otherwise
Cleans up trace resources including values and highlighted SVG elements.
Sets the current point based on direction and index.
ProtectedmapMoves to the nearest point at the specified coordinates (disabled for boxplots).
Concrete implementation of a box plot trace supporting vertical and horizontal orientations. Handles boxplot sections (min, Q1, Q2, Q3, max, outliers) and rotor-based navigation.
This is a pure box plot — violin-specific behavior lives in ViolinBoxTrace.
