[Tioga-users] Help with legend placement on scatter plot

[David MacMahon]

Wow, that was easy!

It might be nice to have a "legend_margins" convenience method in  
FigureMaker...

def legend_margins
   [legend_left_margin, legend_right_margin, legend_top_margin,  
legend_bottom_margin]
end

...assuming it keeps track of such things, but I'm not sure it  
exposes "margin" info.  Perhaps it could use "legend_bottom" etc.  
methods analogous to "frame_bottom" etc.?
