[Bioperl-l] SOLVED Bio::Graphics::Panel make ruler have neg values

[Lincoln Stein]

Hi Kevin,

Since you are modifying the Panel.pm source code, why don't you just go ahead 
and use the current Bio::Graphics development tree? Since 1.5.1 it supports 
negative coordinates. Here's an illustration:

 #!/usr/bin/perl

 use strict;

 use Bio::Graphics;
 use Bio::Graphics::Feature;

 my $whole   = Bio::Graphics::Feature->new(-start=>-200,-end=>+200);
 my $feature = 
Bio::Graphics::Feature->new(-start=>-100,-end=>+100,-strand=>+1);
 my $panel   = Bio::Graphics::Panel->new(-start=> -200,
					 -end  => +200,
					 -width=>800,
					 -pad_left=>10,
					 -pad_right=>10);
 $panel->add_track($whole,
		   -glyph=>'arrow',
		   -double=>1,
		   -tick=>2);
 $panel->add_track($feature,
	 	  -glyph=>'box',
		   -stranded=>1);
 print $panel->png;

 exit 0;

The resulting image is attached.
