class ArrowEdgeDrawer(AbstractEdgeDrawer):

View In Hierarchy

Edge drawer implementation that draws undirected edges as straight lines and directed edges as arrows.

Method draw_directed_edge Draws a directed edge.

Inherited from AbstractEdgeDrawer:

Method __init__ Constructs the edge drawer.
Method draw_loop_edge Draws a loop edge.
Method draw_undirected_edge Draws an undirected edge.
Method get_label_position Returns the position where the label of an edge should be drawn. The default implementation returns the midpoint of the edge and an alignment that tries to avoid overlapping the label with the edge.
Instance Variable context Undocumented
Instance Variable palette Undocumented
Instance Variable VisualEdgeBuilder Undocumented
Static Method _curvature_to_float Converts values given to the 'curved' edge style argument in plotting calls to floating point values.
Method _construct_visual_edge_builder Construct the visual edge builder that will collect the visual attributes of an edge when it is being drawn.
def draw_directed_edge(self, edge, src_vertex, dest_vertex):
overrides igraph.drawing.edge.AbstractEdgeDrawer.draw_directed_edge

Draws a directed edge.

Parameters
edgethe edge to be drawn. Visual properties of the edge are defined by the attributes of this object.
src_vertexthe source vertex. Visual properties are given again as attributes.
dest_vertexthe target vertex. Visual properties are given again as attributes.
