Method: Rubyvis::Vector#initialize

Defined in:
lib/rubyvis/vector.rb

#initialize(x, y) ⇒ Vector

Constructs a pv.Vector for the specified x and y coordinate. This constructor should not be invoked directly; use pv.vector instead.

y&#x27e9;</i>. The intent of this class is to simplify vector math. Note that in performance-sensitive cases it may be more efficient to represent 2D vectors as simple objects with x and y attributes, rather than using instances of this class.

Parameters:

  • x (number) —

    the x coordinate.

  • y (number) —

    the y coordinate.
