Constructs the edge drawer. |
Method | draw |
Draws a directed edge. |

Method | _construct |
Construct the visual edge builder that will collect the visual attributes of an edge when it is being drawn. |
Inherited from AbstractEdgeDrawer
:
Method | get |
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. |
Method | get |
Get the rotation angle of the label to align with the edge. |
Static Method | _curvature |
Converts values given to the 'curved' edge style argument in plotting calls to floating point values. |
Constructs the edge drawer.
Parameters | |
context | a Matplotlib axes object on which the edges will be drawn. |
palette | the palette that can be used to map integer color indices to colors when drawing edges |
Draws a directed edge.
Parameters | |
edge | the edge to be drawn. Visual properties of the edge are defined by the attributes of this object. |
src | the source vertex. Visual properties are defined by the attributes of this object. |
dest | the source vertex. Visual properties are defined by the attributes of this object. |
Draws a loop edge.
The default implementation draws a small circle.
Parameters | |
edge | the edge to be drawn. Visual properties of the edge are defined by the attributes of this object. |
vertex | the vertex to which the edge is attached. Visual properties are given again as attributes. |
Draws an undirected edge.
The default implementation of this method draws undirected edges as straight lines. Loop edges are drawn as small circles.
Parameters | |
edge | the edge to be drawn. Visual properties of the edge are defined by the attributes of this object. |
src | the source vertex. Visual properties are given again as attributes. |
dest | the target vertex. Visual properties are given again as attributes. |
