Fork Description

Author:: Delano Mandelbaum ( Author:: Kalin Harvey Date:: December 12, 2008

We love scruffy. Our motivation for creating a forking is to make it useful for hi-resolution graphs and charts. We would love to get our changes in to the official release but until that time they will be available at the GitHub URI above.

CHANGES.txt contains everything we've been up to.


  • Renders to SVG or bitmap (PNG, JPG)


  • 0.2.3 version has missing legend text when rendering to bitmap. This is strange because the text is there in the SVG before it goes to RMagick.


graph =
graph.title = "Sample Line Graph"
graph.renderer =

graph.add :line, 'Example', [20, 100, 70, 30, 106]

graph.render :to => "line_test.svg"
graph.render  :width => 300, :height => 200,
  :to => "line_test.png", :as => 'png'

Requirements :

  • Needs RMagick and Magic installed, if you wish to render to bitmap.


  • sudo gem install scruffy
