Defining User Themes/Styles

[Joseph Bylund <joseph bylund gmail com>]

What I would like to do is change certain things about  the default
chart layout, i.e. no backpane fill, no chart outline... I see that
there is a theme tab in the graph guru which has a "forget user styles"
button, so perhaps I can define a user style and set that as the
default?  Or is there some way to change the defaults for other
graph/chart properties? Thanks,
-Joe
