Rails - Jul 2006 - Need some Gruff graphing help - custom dimensions?

I''ve been working with Gruff to do all my apps graphing and such etc. 
I
love it but I''m just having a hard time customizing the graphs, but
this
is perhaps due to my inability to comprehend the online RDocs.

What I want to do is adjust the width / heights of my graphs or at the 
VERY LEAST the heights.  It seems that if you scale a graph anywhere 
below 400-450px it is pretty much unreadable, which is very unfortunate 
since I''ve seen so many very nice, small-scale graphs around online 
(such as in web stat packages etc).  So the next best thing I think I 
could do help fit into my layout is atleast make my graph wide-screen 
so-to-speak and not as tall as the default height.

I''ve been searching the docs and I''ve seen many methods that
regard
setting height but every attempts I''ve made to implement in my code 
results in errors.

On the topfunky sample side there is a "wide graph" example which is 
basically just wide and not as tall, it is the second example here:

http://geoffreygrosenbach.com/projects/show/5

How do I do that when working with similar but very simple line graphs? 
Given this sample code below, how would I easily modify the height/width 
or make it a widegraph as in the example above?  Thanks for any help.

data = [1, 2, 3, 4, 5, 6]

g = Gruff::Line.new(500) #Sets scale to 500px, but I''d like 500 width 
and 300 height
g.title = "Samplegraph"
g.labels = {1 => "Today", 3 => "Yesterday", 6 =>
"The Day Before"}
g.theme_37signals

g.data("Graph", data, ''#378CDF'')

g.maximum_value = 10

send_data(g.to_blob, :disposition => ''inline'', :type =>
''image/png'',
:filename => "sample_graph.png
