Loops
=====

This minimal example shows how to style a plot loops.

.. GENERATED FROM PYTHON SOURCE LINES 7-48

    import networkx as nx
    import iplotx as ipx

    # Create a graph and add a self-loop to node 0
    G = nx.complete_graph(3, create_using=nx.DiGraph)
    pos = nx.circular_layout(G)
    ne = G.number_of_edges()

    # Add self-loops to the remaining nodes
    G.add_edge(0, 0)
    edgelist = [(1, 1), (2, 2)]
    G.add_edges_from(edgelist)

    # Style the edge lines
    linestyle = {e: "-" if e not in edgelist else "--" for e in G.edges()}

    ipx.network(
        G,
        layout=pos,
        vertex_labels=True,
        style={
            "vertex": {
                "size": 30,

In addition to fully structured styles in the form of nested dictionaries,
`iplotx` also accepts flat or semi-flat styles, with levels separated by
underscores ("_"). The above is equivalent to:

.. GENERATED FROM PYTHON SOURCE LINES 52-69

.. code-block:: Python


    ipx.network(
        G,
        layout=pos,
        vertex_labels=True,
        style=dict(
            vertex_size=30,
            vertex_facecolor="lightblue",
            vertex_edgecolor="none",
            vertex_label_color="black",
            edge_linestyle=linestyle,
            edge_paralleloffset=0,
            edge_looptension=3.5,
            edge_arrow_marker="|>",
        ),
    )

The `**kwargs` flexible argument of `ipx.plotting` can be used for this purpose as well,
for increased readability:

.. GENERATED FROM PYTHON SOURCE LINES 72-87

.. code-block:: Python


    ipx.network(
        G,
        layout=pos,
        vertex_labels=True,
        vertex_size=30,
        vertex_facecolor="lightblue",
        vertex_edgecolor="none",
        vertex_label_color="black",
        edge_linestyle=linestyle,
        edge_paralleloffset=0,
        edge_looptension=3.5,
        edge_arrow_marker="|>",
    )

The same can be achieved also with a style **context**:

.. GENERATED FROM PYTHON SOURCE LINES 89-105

.. code-block:: Python


    with ipx.style.context(
        vertex_size=30,
        vertex_facecolor="lightblue",
        vertex_edgecolor="none",
        vertex_label_color="black",
        edge_linestyle=linestyle,
        edge_paralleloffset=0,
        edge_looptension=3.5,
        edge_arrow_marker="|>",
    ):
        ipx.network(
            G,
            layout=pos,
            vertex_labels=True,
        )
