Draw edge labels.

Parameters:

Ggraph: A networkx graph
posdictionary: A dictionary with nodes as keys and positions as values. Positions should be sequences of length 2.
edge_labelsdictionary (default=None): Edge labels in a dictionary of labels keyed by edge two-tuple. Only labels for the keys in the dictionary are drawn.
label_posfloat (default=0.5): Position of edge label along edge (0=head, 0.5=center, 1=tail)
font_sizeint (default=10): Font size for text labels
font_colorcolor (default=’k’ black): Font color string. Color can be string or rgb (or rgba) tuple of floats from 0-1.
font_weightstring (default=’normal’): Font weight
font_familystring (default=’sans-serif’): Font family
alphafloat or None (default=None): The text transparency
bboxMatplotlib bbox, optional: Specify text box properties (e.g. shape, color etc.) for edge labels. Default is {boxstyle=’round’, ec=(1.0, 1.0, 1.0), fc=(1.0, 1.0, 1.0)}.
horizontalalignmentstring (default=’center’): Horizontal alignment {‘center’, ‘right’, ‘left’}
verticalalignmentstring (default=’center’): Vertical alignment {‘center’, ‘top’, ‘bottom’, ‘baseline’, ‘center_baseline’}
axMatplotlib Axes object, optional: Draw the graph in the specified Matplotlib axes.
rotatebool (default=True): Rotate edge labels to lie parallel to edges
clip_onbool (default=True): Turn on clipping of edge labels at axis boundaries
node_sizescalar or array (default=300): Size of nodes. If an array it must be the same length as nodelist.
nodelistlist, optional (default=G.nodes()): This provides the node order for the node_size array (if it is an array).
connectionstylestring or iterable of strings (default=”arc3”): Pass the connectionstyle parameter to create curved arc of rounding radius rad. For example, connectionstyle=’arc3,rad=0.2’. See matplotlib.patches.ConnectionStyle and matplotlib.patches.FancyArrowPatch for more info. If Iterable, index indicates i’th edge key of MultiGraph
hide_ticksbool, optional: Hide ticks of axes. When True (the default), ticks and ticklabels are removed from the axes. To set ticks and tick labels to the pyplot default, use hide_ticks=False.

Returns:

dict: dict of labels keyed by edge
