.SH NAME
Ace::Graphics::Glyph::arrow \- The "arrow" glyph
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\&  See L<Ace::Graphics::Panel> and L<Ace::Graphics::Glyph>.
.Ve
.SH DESCRIPTION
.IX Header "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.
.SS OPTIONS
.IX Subsection "OPTIONS"
In addition to the common options, the following glyph-specific
options are recognized:
.PP
.Vb 2
\&  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)
.Ve
.PP
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:
.PP
.Vb 2
\&       ^
\&       |
.Ve
.PP
Otherwise, there will be two arrows at the start and end:
.PP
.Vb 2
\&       ^              ^
\&       |              |
