Method: Gruff::Base#initialize

Defined in:
lib/gruff/base.rb

#initialize(target_width = DEFAULT_TARGET_WIDTH) ⇒ Base

If one numerical argument is given, the graph is drawn at 4/3 ratio according to the given width (800 results in 800x600, 400 gives 400x300, etc.).

Or, send a geometry string for other ratios ( ‘800x400’, ‘400x225’).

Parameters:

  • target_width (Numeric, String) (defaults to: DEFAULT_TARGET_WIDTH) —

    The graph image width.
