Struct Arrows 

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

A set of arrows.

Implementations

impl<'a> Arrows<'a>

pub fn new( name: impl Into<String>, origins: impl Into<PlotPoints<'a>>, tips: impl Into<PlotPoints<'a>>, ) -> Self

pub fn tip_length(self, tip_length: f32) -> Self

Set the length of the arrow tips

pub fn color(self, color: impl Into<Color32>) -> Self

Set the arrows’ color.

pub fn name(self, name: impl ToString) -> Self

Name of this plot item.

This name will show up in the plot legend, if legends are turned on.

Setting the name via this method does not change the item’s id, so you can use it to change the name dynamically between frames without losing the item’s state. You should make sure the name passed to Self::new is unique and stable for each item, or set unique and stable ids explicitly via Self::id.

pub fn highlight(self, highlight: bool) -> Self

Highlight this plot item, typically by scaling it up.

If false, the item may still be highlighted via user interaction.

pub fn allow_hover(self, hovering: bool) -> Self

Allowed hovering this item in the plot. Default: true.

pub fn id(self, id: impl Into<Id>) -> Self

Sets the id of this plot item.

By default the id is determined from the name passed to Self::new, but it can be explicitly set to a different value.

Trait Implementations

impl PlotItem for Arrows<'_>

fn shapes(&self, _ui: &Ui, transform: &PlotTransform, shapes: &mut Vec<Shape>)

Generate shapes to be drawn in the plot.

fn initialize(&mut self, _x_range: RangeInclusive<f64>)

For plot-items which are generated based on x values (plotting functions).

fn color(&self) -> Color32

Returns the color of the plot item.

fn geometry(&self) -> PlotGeometry<'_>

Returns the geometry of the plot item.

fn bounds(&self) -> PlotBounds

Returns the bounds of the plot item.

fn base(&self) -> &PlotItemBase

Returns a reference to the base data of the plot item.

fn base_mut(&mut self) -> &mut PlotItemBase

Returns a mutable reference to the base data of the plot item.

fn name(&self) -> &str

Returns the name of the plot item.

fn highlight(&mut self)

Highlight the plot item.

fn highlighted(&self) -> bool

Returns whether the plot item is highlighted.

fn allow_hover(&self) -> bool

fn id(&self) -> Id

Returns the ID of the plot item.

fn find_closest( &self, point: Pos2, transform: &PlotTransform, ) -> Option<ClosestElem>

Find the closest element in the plot item to the given point.

fn on_hover( &self, plot_area_response: &Response, elem: ClosestElem, shapes: &mut Vec<Shape>, cursors: &mut Vec<Cursor>, plot: &PlotConfig<'_>, label_formatter: &Option<LabelFormatter<'_>>, )

Handle hover events for the plot item.
