[Biojava-l] bioperl graph - different glyph on the same track

[hz5 at njit.edu]

Hi everybody,
I want to generate something like this:
    _________            ____________
----|        |-----------|           |-----
    ---------            -------------

segments are colored differently, if I use cds, or segments glyph type, the 
whole thing is one feature, cannot be colored differently, also the line will 
ends where the box(HSP or exon) ends, it won't extent to indicate the full 
length of the sequence.

if I use a set of features for each segments and display them on one track, 
then they can be colored differently, but the lines cannot be displayed, if I 
render lines as features as well, glyph type will be line, then they cannot 
occupy the same track.

How should I do it?

I am sure other people have this problem before, sorry for ask again.

Thanks!
