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 methodsize’ for nil:NilClass (NoMethodError)”
Anyone have any idea on how I could add the fourth field to the graph?
Thanks.
