NAME

Bio::Graphics::Glyph::broken_line - The "broken line" glyph

SYNOPSIS

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

DESCRIPTION

This glyph draws a straight line whose segment is shifted ("sheared") up or down. There can be an optional "break" (two diagonal lines passing between the main line and its segment). Either the left or the right side of the main line can be absent. The line can be of fixed size or extend to take up all available space.
