Ace::Graphics::Glyph::arrow - The "arrow" glyph
See L<Ace::Graphics::Panel> and L<Ace::Graphics::Glyph>.
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.
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:
