我有一段旧的 plotly 代码，我收到一条错误消息，指出 plotly 已迁移到图表工作室，我刚刚开始了一个网络分析项目，并且为了可视化我已经拥有的所述/给定数据是在旧版本的 plotly 中完成。请帮助我查看了 plotly 文档，但我不明白它的工作原理。

Answer 1

两个核心建议

1. 使用字典而不是对象（即不需要Margin、Data等）
2. 使用标准导入 import plotly.graph_objects as go 提高对象范围的清晰度

我预先定义了您的代码使用的变量。 dot 不再是一个有效的标记 symbol 替换为 square

import plotly.graph_objects as go

# define some input data...
t = np.linspace(0, 10, 50)
Xe, Ye, Ze = np.cos(t), np.sin(t), t
Xn = Xe * 2
Yn = Ye * 2
Zn = Ze * 2
eigen = t
labels = ["a"]

trace1 = go.Scatter3d(
    x=Xe,
    y=Ye,
    z=Ze,
    mode="lines",
    line=dict(color="rgb(125,125,125)", width=1),
    hoverinfo="none",
)

trace2 = go.Scatter3d(
    x=Xn,
    y=Yn,
    z=Zn,
    mode="markers",
    name="actors",
    marker=dict(
        symbol="square",
        color=eigen,
        size=6,
        colorbar=dict(title="Colorbar"),
        colorscale="Viridis",
        line=dict(color="rgb(158,18,130)", width=0.5),
    ),
    text=labels,
    hoverinfo="text",
)

axis = dict(
    showbackground=False,
    showline=False,
    zeroline=False,
    showgrid=False,
    showticklabels=False,
    title="",
)

layout = go.Layout(
    title="3D Visualization of the Facebook nodes",
    width=1000,
    height=1000,
    showlegend=False,
    scene=dict(
        xaxis=axis,
        yaxis=axis,
        zaxis=axis,
    ),
    margin={"t": 100},  # go.Margin(t=100),
    hovermode="closest",
    annotations=[
        dict(
            showarrow=False,
            text=
            "Data source: <a href='http://bost.ocks.org/mike/miserables/miserables.json'>[1] miserables.json</a>",
            xref="paper",
            yref="paper",
            x=0,
            y=0.1,
            xanchor="left",
            yanchor="bottom",
            font=dict(size=14),
        )
    ],
)

fig = go.Figure(data=[trace1, trace2], layout=layout)
