Have a quick Gruff Graphing question

g.maximum_value = 10
send_data(g.to_blob, :disposition => ''inline'', :type => ''image/png'',
:filename => "sample_graph.png

Limit attributes written out by to_yaml

- !ruby/object:Item
attributes:
image_height: ''''
maximum_value: ''''
minimum_value: ''''
item_id: 153
default_value: ''''
... many more fields
However I don''t want all these fields. How can I limit the YAML output
to just include the fields that I want?
I know that I can over...
