Required Methods

fn paint(&mut self, bounds: Bounds<Pixels>, window: &mut Window, cx: &mut App)

Provided Methods

fn prepaint( &mut self, _bounds: Bounds<Pixels>, _window: &mut Window, _cx: &mut App, ) -> Vec<AnyElement>

Lay out and place the child elements this plot hosts (e.g. element labels).

Called during the element’s prepaint phase, so implementations may use AnyElement::layout_as_root / AnyElement::prepaint_at to measure and position children — neither is legal from Plot::paint. The returned elements are painted right after paint, below the tooltip overlay.

Runs before Plot::tooltip_state and Plot::tooltip, so anything resolved here can be reused by them.

The default returns no children.

fn id(&self) -> Option<ElementId>

A stable element id that enables interactive tooltip support for this plot.

Return Some(id) to opt in to tooltips; the id must be unique among sibling elements. Returning None (the default) disables all tooltip behavior, leaving the plot a pure, non-interactive element identical to the pre-tooltip behavior.

fn tooltip_state( &self, _position: Point<Pixels>, _bounds: Bounds<Pixels>, _cx: &App, ) -> Option<TooltipState>

Map the cursor to the tooltip state to display.

position is the cursor position relative to the plot’s top-left origin (already origin-subtracted), and bounds is the painted area. Return the TooltipState to display (highlighted index, crosshair point, dots, side), or None to show nothing. Only called while the cursor is inside bounds.

The default returns None.

fn tooltip( &self, _state: &TooltipState, _cursor: Point<Pixels>, _bounds: Bounds<Pixels>, _window: &mut Window, _cx: &mut App, ) -> Option<AnyElement>

Render the tooltip overlay for the active TooltipState.

cursor is the live cursor position (relative to the plot origin) and bounds is the plot’s painted area, so the tooltip box can follow the cursor (pass cursor and bounds.size to tooltip::Tooltip::new). Return the overlay element; it is painted absolutely positioned above the plot graphics but below sibling content drawn after the plot (tooltip::Tooltip defers its box to paint above everything). The default returns None.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
