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

[David MacMahon]

Quick question: Must one know in advance how many legend entries  
there will be so that legend_bottom_margin can be set appropriately  
(assuming the legend starts near the top)?  If so, how does one  
calculate the legend height?  Presumably, legend_bottom_margin = 1.0  
- legend_top_margin - legend_height, where legend_height depends on  
the number of entries and each entry's height.

Thanks,
Dave
