Struct PlotView 

pub struct PlotView<'a> { /* private fields */ }

Stateless view that renders a Plot into an egui Ui.

Implementations

impl<'a> PlotView<'a>

pub fn new() -> Self

Create a new plot view.

pub fn with_context_menu(self, ext: &'a mut dyn FnMut(&mut Ui)) -> Self

Append custom entries to the plot’s built-in right-click context menu, after the Zoom Back / Reset Zoom items. See Self::menu_ext for why this hook (and not a second Response::context_menu) is the way to add custom menu entries.

pub fn show(self, ui: &mut Ui, plot: &mut Plot) -> PlotResponse

Render the plot with the default zoom interaction mode, filling the available space. Returns the egui response and the display transform used this frame.

pub fn zoom_back(&self, plot: &mut Plot) -> bool

Restore the previously stored view from the limits history, mirroring silx ZoomBackAction (getLimitsHistory().pop()). Returns true if a stored view was restored, false if the history was empty. The toolbar zoom-back button (a later wave) calls through this.

pub fn show_with_interaction( self, ui: &mut Ui, plot: &mut Plot, interaction_mode: PlotInteractionMode, ) -> PlotResponse

Render the plot with an explicit primary-pointer interaction mode.

pub fn show_with_draw( self, ui: &mut Ui, plot: &mut Plot, draw: &mut DrawState, style: SelectionStyle, ) -> DrawResponse

Render the plot in a draw/select mode driven by draw, painting the in-progress shape as a rubber-band overlay and returning any DrawEvent produced this frame.

The plot is shown in PlotInteractionMode::Select so a primary drag feeds the draw state machine instead of box-zooming (secondary drag still pans, wheel still zooms). Press / move / release on the data area are fed to draw (silx Select* onPress / onMove / onRelease); the resulting preview/finished shape is drawn with style (silx setSelectionArea, PlotInteraction.py:98-141).

Wiring a Finished event to ROI / mask creation is left to the caller (silx high-level widgets / mask tools).

Trait Implementations

impl<'a> Default for PlotView<'a>

fn default() -> PlotView<'a>

Returns the “default value” for a type.
