Basics of styling

This example shows a few simple styling options available in iplotx.

Tip

iplotx has an internal library of styles. See the Style library example.

import igraph as ig
import matplotlib.pyplot as plt
import iplotx as ipx

g = ig.Graph.Ring(5)
layout = g.layout("circle")
style = {
    "vertex": {
        "facecolor": ["purple", "pink", "black"],
        "edgecolor": "black",
    },
    "edge": {
        "linestyle": "--",
        "linewidth": 2,
        "color": "deeppink",
    },
}
fig, ax = plt.subplots(figsize=(3, 3))
ipx.network(g, ax=ax, layout=layout, style=style)

[<iplotx.network.NetworkArtist object at 0x7dd1a6045bd0>]

You can also chain styles. For example, you can apply an existing style first, and then modify it with a custom dictionary:

style = {
    "edge": {
        "linestyle": "--",
    },
}
fig, ax = plt.subplots(figsize=(3, 3))
ipx.network(
    g,
    ax=ax,
    layout=layout,
    style=["rededge", style],
)

[<iplotx.network.NetworkArtist object at 0x7dd1a600ca50>]

As you can see, the network is visualised with the “rededge” style (which has red, solid edges) but further modified to have dashed lines.
