[Bioperl-l] Bio::Graphics::Glyph::arrow negative coordinates

[Steffen Grossmann]

Dear wizards,

I wonder whether it is possible to draw a Bio::Graphics::Glyph::arrow 
along the whole of a sequence with coordinates in the negative region.

Clearly, the default behaviour is that the arrow starts with 1 on the 
left side and ends with the length of the sequence on the other end.
If I now use '-scale => -1' I get negative coordinates, but these 
decrease from left to right!

What I want are negative coordinates which _increase_ from left to right 
and start at -$seq->length and end at -1.

Can this be done?

Thanks a lot!

Steffen
