Symbol class Symbols

Symbols provide a categorical shape encoding as in a scatterplot.

Symbols are centered at the origin; use a transform to move the symbol to a different position.

Constructors

Symbol.new({SymbolType type(Symbol, [List<Object?>?])?, num size(Symbol, [List<Object?>?])?})

Constructs a new symbol generator of the specified type and size accessors.

Symbol.withConstants({SymbolType? type, num? size})

Constructs a new symbol generator of the specified type and size.

Properties

context ↔ Path?

Optional context for rendering the generated symbol (see Symbol.call) as a sequence of path method calls.
