Scruffy::Helpers::LayerContainer

Author:Brasten Sager
Date:August 16th, 2006

Adds some common functionality to any object which needs to act as a container for graph layers. The best example of this is the Scruffy::Graph object itself, but this module is also used by Scruffy::Layer::Stacked.

Methods

<<   add   layers   layers=  

Public Instance methods

<<(*args, &block)

Adds a Layer to the Graph/Container. Accepts either a list of arguments used to build a new layer, or a Scruffy::Layers::Base-derived object. When passing a list of arguments, all arguments are optional, but the arguments specified must be provided in a particular order: type (Symbol), title (String), points (Array), options (Hash).

Both add and #<< can be used. 

  graph.add(:line, [100, 200, 150])     # Create and add an untitled line graph

  graph << (:line, "John's Sales", [150, 100])    # Create and add a titled line graph

  graph << Scruffy::Layers::Bar.new({...})   # Adds Bar layer to graph
add(*args, &block)
