[Bioperl-l] xyplot weirdness

[Tobias]

hi,

when trying to use xy-plot (boxes) in gbrowse I get unpredictable 
rendering of the scores. if I set a set the scores of all subfeatures 
that I aggregate to the same value (i.e. 5) the boxes are not rendered 
at all, means they have a height of zero. when I change the value of 
one subfeature to a different value (i.e. 3), all but this subfeature 
are rendered properly. the changed subfeature gets a box of zero 
height, while the other ones now have a clear 5. furthermore this 
behaviour changes (i did not say improve) when changing zoom levels. 
sometimes, not always.
I'm using bioperl v. 1.302 and gbrowse v. 1.54

looks like a bug, a known-one?

cheers
Tobias
