Enum ChartSource 

pub enum ChartSource<T: 'static> {
    Model(ChartModel<T>),
    Window(ChartWindow<T>),
}

A reactive chart input. Conversions retain shared handles and copy no points.

Window point indices (including hover and selection indices) are local to the visible tail. A window bounds the displayed data, not source storage.

Variants

Model(ChartModel<T>)

All points in the model.

Window(ChartWindow<T>)

The last configured number of points in each series.

Implementations

impl<T: 'static> ChartSource<T>

pub fn with_all_series<R>(&self, f: impl FnOnce(&[SeriesView<'_, T>]) -> R) -> R

Read the visible series and borrowed point slices.

pub fn with_series_view<R>( &self, series: SeriesId, f: impl FnOnce(SeriesView<'_, T>) -> R, ) -> Option<R>

Read one visible series, using window-local point indices.

pub fn with_series<R>( &self, series: SeriesId, f: impl FnOnce(&str, Option<&ColorProp>, bool) -> R, ) -> Option<R>

Read series metadata from the source.

pub fn set_series_visible(&self, series: SeriesId, visible: bool)

Change source visibility, for interactive legends.

pub fn series_ids(&self) -> Vec<SeriesId>

Ordered series identifiers.

pub fn series_count(&self) -> usize

Number of series, including hidden series.

pub fn series_id_at(&self, index: usize) -> Option<SeriesId>

Series at the given display position.

pub fn only_series(&self) -> Option<SeriesId>

Sole series, when the source has exactly one.

pub fn point_count(&self, series: SeriesId) -> usize

Number of visible points in a series.

pub fn structure_version(&self) -> Signal<u64>

Reactive version for geometry and accessible data.

pub fn style_version(&self) -> Signal<u64>

Reactive version for colors and patterns.

pub fn observe_changes( &self, f: impl Fn(&ChartChange) + 'static, ) -> ObserverHandle

Observe changes using indices relative to this input.
