要实现 Plotly 的动态雷达图,需要使用 `animation` 模块。下面是一个简单的例子:
首先,导入所需的库:
```python
import plotly.graph_objs as go
import plotly.offline as pyo
import numpy as np
```
然后,生成随机数据:
```python
data = []
for i in range(5):
data.append(np.random.randint(1, 10, 10))
```
接下来,定义一个函数来生成动态图:
```python
def update_radar(i):
traces = []
for j in range(5):
traces.append(go.Scatterpolar(
r=data[j][:i+1],
theta=[k * 360/10 for k in range(10)],
mode='lines+markers',
name='trace {}'.format(j)
))
layout = go.Layout(
polar=dict(
radialaxis=dict(
visible=True,
range=[0, 10]
)
),
showlegend=False
)
fig = go.Figure(data=traces, layout=layout)
pyo.plot(fig, filename='dynamic_radar.html')
```
接下来,使用 `animation` 模块创建动画对象:
```python
frames = [go.Frame(data=[go.Scatterpolar(
r=[data[j][i]],
theta=[k * 360/10 for k in range(10)],
mode='markers',
marker=dict(color='red', size=10),
name='trace {}'.format(j)
)]) for i in range(10) for j in range(5)]
```
最后,创建动画并播放:
```python
fig = go.Figure(
data=[go.Scatterpolar(
r=[0] * 10,
theta=[k * 360/10 for k in range(10)],
mode='lines',
line=dict(color='black')
)],
layout=go.Layout(
polar=dict(
radialaxis=dict(
visible=True,
range=[0, 10]
)
),
showlegend=False
),
frames=frames
)
fig.layout.updatemenus[0].buttons[0].args[1]['frame']['duration'] = 500
fig.layout.updatemenus[0].buttons[0].args[1]['frame']['redraw'] = True
pyo.plot(fig, filename='dynamic_radar.html')
```
当你运行这段代码后,你将会看到一个动态的雷达图,它会展示随机生成的数据。
