MSparkline class

A line chart of a bound numeric series — the "how has this moved" glance a price, step count, or temperature widget is built around.

The bound value is a list of numbers pushed with MosaicBridge.saveList('key', [1, 2, 3]). Values are normalised across the series, so only the shape matters, not the absolute range.

Rendering differs by necessity: SwiftUI draws a real Path, while RemoteViews cannot draw vectors at all — the Android provider rasterises the series to a bitmap at update time and sets it on an ImageView. Both give the same picture; only the Android one is resolution-fixed.

Fewer than two points renders nothing, since a line needs two ends.

MSparkline({required MBind bind, MColor? color, double strokeWidth = 2, bool fill = false, double? height})

const

Properties

bind → MBind

Bound key holding the list of numbers.

final

color → MColor?

Stroke colour. Bound colours are not supported here — the Android bitmap is rasterised with a fixed paint.

final

fill → bool

Translucent fill under the line.

final

hashCode → int

The hash code for this object.

no setter, inherited

height → double?

Fixed height; without it the chart fills the space it is given.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

strokeWidth → double

Stroke width in logical pixels.

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, dynamic>

override

toString() → String

A string representation of this object.
