Hi everybody, I''m using scruffy to create some graphs, and would like to integrate them into a regular view (i.e. show them in an <img> tag). However, I get errors when using img_tag, or the image doesn''t load if I try saving the graph to disk and then loading them in html. Generating the graph and linking to it works, however then I only have the graph open in a new window, whereas I''d like to use the graph as an image inside an html page. Any pointers on how to do this? I''ve searched around the ibrasten website, and scruffy itself works just fine, but I''ve been unable to locate any information on how to integrate scruffy into rails. Any links would be most appreciated.

Hi Elmar,
I''m using scruffy successfully in my project, here is what I do. I
have this in a helper of mine (you could put it in
application_helper.rb or wherever it''s fine for you)
def render_scruffy_graph(options = nil)
opts = make_options(options)
graph = Scruffy::Graph.new
# add the Scruffy::Layers you would like to use
graph.add :bar, opts[:data]
graph.point_markers = opts[:markers]
graph.renderer = opts[:renderer]
graph.render(
:size => options[:size],
:min_value => opts[:data].first, # you might not need this one
:max_value => opts[:data].last, # you might not need this one
:theme => opts[:theme], # you might not need this one
:as => opts[:img_format],
:to => opts[:filename]
)
end
private
# options specified here possibly
# override options passed in parameter
def make_options(options = nil)
opts = options ? {}.merge(options) : {}
returning opts do |o|
# add o[:foo] = bar statements as you wish (look @ the options
that graph.render supports)
# you can specify :renderer and :theme like so
o[:renderer] = Scruffy::Renderers::YourRenderer.new
o[:theme] = Scruffy::Themes::YourTheme.new
end
end
There are definitely more flexible ways for generating your options,
but this did the trick for me ..
Then in the view just call
<%= render_scruffy_graph %>
Hope this helps

Oops forgot something, Be sure not to use :as => "svg" if you want svg images. Scruffy''s default is to use svg anyway, and if I recall correctly, something went wrong when supplying :as => "svg", :to => "blabla.svg". Just use the :to option if you want to render svg images to files. cheers Martin Gamsjäger On Feb 20, 3:01 pm, "Martin Gamsjaeger" <gamsnj...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hi Elmar, > > I''m using scruffy successfully in my project, here is what I do.
