Fields

unit_fmt: UnitFmt

Implementations

impl<X: Axis<X>, Y: Axis<Y>> LinePlot<X, Y>

pub fn new_widget(
    ctx: &EventCtx<'_>,
    label: &str,
    series: Vec<Series<X, Y>>,
    opts: PlotOptions<X, Y>,
    unit_fmt: UnitFmt
) -> Widget

label is used to name the actual LinePlot widget. The result of this call can’t be usefully named, since the plot is wrapped in some containers for formatting.

pub fn get_hovering(&self) -> Vec<(X, Y)>

pub fn set_hovering(&mut self, ctx: &mut EventCtx<'_>, label: &str, x: X, y: Y)

Programmatically show a tooltip at the given x/y.

Useful (e.g.) when points on the line plot corresponds to a point on the map - as the user hovers on the map you can highlight the corresponding details on the plot.

Trait Implementations

impl<X: Axis<X>, Y: Axis<Y>> WidgetImpl for LinePlot<X, Y>

fn get_dims(&self) -> ScreenDims

What width and height does the widget occupy? If this changes, be sure to set redo_layout to true in event.

fn set_pos(&mut self, top_left: ScreenPt)

Your widget’s top left corner should be here. Handle mouse events and draw appropriately.

fn event(&mut self, ctx: &mut EventCtx<'_>, _: &mut WidgetOutput)

Your chance to react to an event. Any side effects outside of this widget are communicated through the output.

fn draw(&self, g: &mut GfxCtx<'_>)

Draw the widget. Be sure to draw relative to the top-left specified by set_pos.

fn can_restore(&self) -> bool

If a new Panel is being created to replace an older one, all widgets have the chance to preserve state from the previous version.

fn restore(&mut self, _: &mut EventCtx<'_>, _prev: &dyn WidgetImpl)

Restore state from the previous version of this widget, with the same ID. Implementors must downcast.
