Line<T> class Lines

The line generator produces a spline or polyline as in a line chart.

Lines also appear in many other visualization types, such as the links in hierarchical edge bundling. See also radial lines.

Constructors

Line.new(num x(T, int, List<T>), num y(T, int, List<T>)): Constructs a new line generator with the given x and y accessor.
Line.withConstants(num x, num y): Constructs a new line generator with the given x and y numbers.

context ↔ Path?: Optional context for rendering the generated line (see Line.call) as a sequence of path method calls.
getter/setter pairinherited-setter
curve ↔ CurveFactory: The curve factory.
getter/setter pairinherited-setter
defined ↔ bool Function(T, int, List<T>): When a line is generated (see Line.call), the defined accessor will be invoked for each element in the input data list, being passed the element d, the index i, and the list data as three arguments.
getter/setter pairinherited-setter
digits ↔ num?: The maximum number of digits after the decimal separator.
getter/setter pairinherited-setter
hashCode → int: The hash code for this object.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.

x ↔ num Function(T, int, List<T>): When a line is generated (see Line.call), the x accessor will be invoked for each defined element in the input data list, being passed the element d, the index i, and the list data as three arguments.
getter/setter pair
y ↔ num Function(T, int, List<T>): When a line is generated (see Line.call), the y accessor will be invoked for each defined element in the input data list, being passed the element d, the index i, and the list data as three arguments.

call(List<T> data) → String?: Generates a line for the given list of data.
constDefined(bool defined) → void: Defines the Line.defined-accessor as a constant function that always returns the specified value.
constX(num x) → void: Defines the Line.x-accessor as a constant function that always returns the specified value.
constY(num y) → void: Defines the Line.y-accessor as a constant function that always returns the specified value.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.

withDefaults({num x(List<num>, int, List<List<num>>) = pointX, num y(List<num>, int, List<List<num>>) = pointY}) → Line<List<num>>: Equivalent to Line.new, except that if x or y are not specified, the respective defaults will be used.
