Hi Sean,
Did your plugin break when you upgraded to GBrowse 1.7, or when you upgraded
bioperl? Knowing this will help me figure out where to look for the problem.
It frankly looks like a database problem in the sense that the xyplot glyph
is trying to render 100 features rather than a feature with 100 parts.
Are you sure this step is correct?
$feature_list->add_type($matrix=>{glyph => 'xyplot',
> graph_type => 'boxes',
> scale => 'auto',
> height => 40,
> bump => 0,
> min_score=>0,
> max_score=>$maxscore,

> fgcolor => $COLORS[$i % @COLORS],
> bgcolor => $COLORS[$i % @COLORS],
> });
It seems to me you intend to add the $feature, not the $matrix variable.
