Hi everyone,

I'd like to use RGB notation when using part_color.
I tried that :

[MyFeature]
feature = MyFeature
glyph           = xyplot
graph_type      =  boxes
label           = 0
part_color   = sub {
                my $feat = shift;
                if($feat->has_tag('MyTag')) {
                        return rgb(150,150,0);
                }
                else{
                        return 'grey';
                }
        }
max_score       = 3
min_score       = -3
key             = MyFeatureKey
group_on = display_name
height          =100
bump    =0

Unfortunately it didnt work.
Here is the error.log :
Error returned while evaluating value of 'part_color' option for glyph Bio::Graphics::Glyph::xyplot=HASH(0x98bb348), feature MyFeature:MySource(MyType): Undefined subroutine &Bio__Graphics__BrowserConfig_HASH_0x9083850_::rgb called at (eval 87) line 3.

I tried to add "use Bio::Graphics::Panel;" in the xyplot.pm file ... no succes.
Any idear anyone?

Hi Alesk,

Here's what the perldoc for Bio::Graphics::Panel says about the rgb method:

           This method is only useful within a
           glyph’s draw() routine, after the panel has allocated a GD::Image
           and is populating it.

and it's not clear to me that the callback is evaluated in this
context, which is why you don't have access to that method.  Instead,
I suggest you use the html # notation, but instead of writing the "#"
character (because that causes problems too), write it as a char:

  return chr(35)."686800";
