Method: Rubyvis::Layout::Partition#size

Defined in:
lib/rubyvis/layout/partition.rb

#size(f = nil, &block) ⇒ Object

Specifies the sizing function. By default, a sizing function is disabled and all nodes are given constant size. The sizing function is invoked for each leaf node in the tree (passed to the constructor).

<p>For example, if the tree data structure represents a file system, with files as leaf nodes, and each file has a bytes attribute, you can specify a size function as:

<pre> .size(function(d) d.bytes)</pre>

As with other properties, a size function may specify additional arguments to access the data associated with the layout and any enclosing panels.

Parameters:

  • f (function) (defaults to: nil) —

    the new sizing function.
