plotly动态雷达图实例源代码

以下是一个使用 Plotly 绘制动态雷达图的示例代码：

import plotly.graph_objs as go
import numpy as np

# 创建数据
theta = np.linspace(0, 2*np.pi, 6)
r = np.random.randint(1, 10, size=(10, 6))

# 创建轨迹
data = [go.Scatterpolar(
    r = r[i],
    theta = theta,
    mode = 'lines',
    fill = 'toself'
) for i in range(10)]

# 创建布局
layout = go.Layout(
    polar = dict(
        radialaxis = dict(
            visible = True,
            range = [0, 10]
        )
    ),
    showlegend = False,
    updatemenus = [dict(
        type = 'buttons',
        showactive = False,
        buttons = [dict(
            label = 'Play',
            method = 'animate',
            args = [None, dict(frame=dict(duration=50, redraw=True), fromcurrent=True)]
        ), dict(
            label = 'Pause',
            method = 'animate',
            args = [[None], dict(frame=dict(duration=0, redraw=False), mode='immediate', transition=dict(duration=0))]
        )]
    )]
)

# 创建帧
frames = [go.Frame(
    data = [go.Scatterpolar(
        r = r[i],
        theta = theta,
        mode = 'lines',
        fill = 'toself'
    )],
    traces = [i],
    name = str(i)
) for i in range(1, 10)]

# 添加帧到布局
layout.update(frames=frames)

# 创建 Figure 对象
fig = go.Figure(data=data, layout=layout)

# 显示图像
fig.show()

该代码将生成一个动态雷达图，其中包含 10 个数据集，每个数据集都包含 6 个数据点。通过单击“Play”按钮，您可以开始动画并观察数据集的变化。
