Scruffy Stacked Bar help

Discussion in 'Ruby' started by Jorge Rodriguez, Jun 7, 2007.

  1. I am trying to graph a stacked bar graph with four "fields" per bar, it
    works fine for up to three fields but when I try to add the fourth field
    I get this error:
    "/usr/local/lib/ruby/gems/1.8/gems/scruffy-0.2.2/lib/scruffy/layers/stacked.rb:71:in
    `points': undefined method `size' for nil:NilClass (NoMethodError)"
    Anyone have any idea on how I could add the fourth field to the graph?
    Thanks.
