MBarChart class

A bar chart of a bound numeric series — step counts, weekly totals, hourly rainfall: the "how much per bucket" glance.

The bound value is a list of numbers pushed with MosaicBridge.saveList('key', [1, 2, 3]).

Unlike MSparkline, bars are scaled from zero, not from the series minimum: a bar's length is read as its magnitude, so starting the axis at the smallest value would overstate small differences. A series with no positive value therefore renders empty.

Rendering matches MSparkline: SwiftUI draws real shapes, while the Android provider rasterises to a bitmap because RemoteViews cannot draw vectors.

Properties

bind → MBind

Bound key holding the list of numbers.

final

color → MColor?

Bar colour. A literal, for the same reason as MSparkline.color.

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

radius → double

Corner radius on each bar.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

spacing → double

Gap between bars, 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.
