ruby - Rubyvis in Rails -

i making project using rails , need make charts thinking using rubyvis.

if have following code in controller:

require 'rubyvis'  vis = rubyvis::panel.new    width 150   height 150    bar     data [1, 1.2, 1.7, 1.5, 0.7, 0.3]     width 20     height {|d| d * 80}     bottom(0)     left {index * 25}   end    end  vis.render     puts vis.to_svg 

how should put output in view?

generating svg file @ runtime wish display in rendered view not should done within controller.

instead, create new method in app/helpers/application_helper.rb or helper specific controller action.

require "rubyvis"  class applicationhelper   def some_method     vis = rubyvis::panel.new      width 150     height 150      bar       data [1, 1.2, 1.7, 1.5, 0.7, 0.3]       width 20       height {|d| d * 80}       bottom(0)       left {index * 25}       end        end      vis.render         vis.to_svg   end end 

and in view can call following wherever wish dump svg data.

<%= some_method %>
