Ace::Graphics::Glyph::arrow.3pm

NAME

Ace::Graphics::Glyph::arrow - The "arrow" glyph

SYNOPSIS

   See L<Ace::Graphics::Panel> and L<Ace::Graphics::Glyph>.
 
 

DESCRIPTION

This glyph draws arrows. Depending on options, the arrows can be labeled, be oriented vertically or horizontally, or can contain major and minor ticks suitable for use as a scale.

OPTIONS

In addition to the common options, the following glyph-specific options are recognized:

   Option      Description               Default
   ------      -----------               -------
 
   -tick       Whether to draw major       0
               and minor ticks.
               0 = no ticks
               1 = major ticks
               2 = minor ticks
 
   -parallel   Whether to draw the arrow   true
               parallel to the sequence
               or perpendicular to it.
 
   -northeast  Whether to draw the         true
               north or east arrowhead
               (depending on orientation)
 
   -southwest  Whether to draw the         true
               south or west arrowhead
               (depending on orientation)
 
 

Set -parallel to false to display a point-like feature such as a polymorphism, or to indicate an important location. If the feature start == end, then the glyph will draw a single arrow at the designated location:

        ^
        |
 
 

Otherwise, there will be two arrows at the start and end:

        ^              ^
        |              |
 
 

BUGS

Please report them.
