我有一個奇怪的問題 - 不確定這是一個錯誤還是我遺漏了什么。當繪制子圖并Code 1為每個子圖分配自定義標題時 - 我稍后嘗試添加到底部圖的注釋沒有完全顯示，但只顯示最后兩個 ( Output Plot 1)。代碼 1：import numpy as npfrom plotly.subplots import make_subplotsfrom math import expfig = make_subplots(2, 1, subplot_titles=['Activation', 'Prediction errors - Model, ALO and RND'])x = np.linspace(0, 10, 100)y = np.array(list(map(lambda x: 1 / (1 + exp(-0.1 * x + 5)), x)))fig.add_trace( go.Scatter( x=x, y=y, name=f'\N{Greek Small Letter Sigma}(x)', showlegend=True ), row=1, col=1)fig['layout']['xaxis'].update(title_text='x')for i in range(4): x = np.where(np.random.randint(0, 2, 100)==1)[0] fig.add_trace( go.Scatter( x=x, y=np.zeros_like(x) + i, name=f'Plot {i}', mode='markers', marker=dict( symbol='circle-open', color='green', size=5 ), showlegend=True ), row=2, col=1 )fig['layout']['xaxis2'].update(title_text='active users', range=[0, 10], autorange=True)fig['layout']['yaxis2'].update(title_text='active users', visible=False, autorange=True)fig['layout'].update( annotations=[ dict(x=0, y=0.125, xref='x2', yref='y2', text='True activity', font=dict(size=10, color='green')), dict(x=0, y=1.125, xref='x2', yref='y2', text='Model', font=dict(size=10, color='blue')), dict(x=0, y=2.125, xref='x2', yref='y2', text='ALO', font=dict(size=10, color='red')), dict(x=0, y=3.125, xref='x2', yref='y2', text='RND', font=dict(size=10, color='black')), ])fig.show()輸出圖 1另一方面，如果我刪除自定義繪圖標簽 - 一切都按預期工作，如Code 2和輸出所示Image 2。

我不確定這是否是由于字幕設置引起的，但是add_annotation()是正確的，update(annotations=[]可能已被函數覆蓋以更新已設置的注釋。
import plotly.graph_objects as go
import numpy as np
from plotly.subplots import make_subplots
from math import exp
fig = make_subplots(2, 1, subplot_titles=('Activation', 'Prediction errors - Model, ALO and RND'))
x = np.linspace(0, 10, 100)
y = np.array(list(map(lambda x: 1 / (1 + exp(-0.1 * x + 5)), x)))
fig.add_trace(
go.Scatter(
x=x,
y=y,
name=f'\N{Greek Small Letter Sigma}(x)',
showlegend=True
),
row=1,
col=1
)
fig['layout']['xaxis'].update(title_text='x')
for i in range(4):
x = np.where(np.random.randint(0, 2, 100)==1)[0]
fig.add_trace(
go.Scatter(
x=x,
y=np.zeros_like(x) + i,
name=f'Plot {i}',
mode='markers',
marker=dict(
symbol='circle-open',
color='green',
size=5
),
showlegend=True
),
row=2,
col=1
)
fig['layout']['xaxis2'].update(title_text='active users', autorange=True)
fig['layout']['yaxis2'].update(title_text='active users', visible=True, range=[-1,4])
fig.add_annotation(
dict(x=0, y=3.125, xref='x2', yref='y2', text='RND', showarrow=True, font=dict(size=10, color='black'))
)
fig.add_annotation(
dict(x=0, y=2.125, xref='x2', yref='y2', text='ALO', showarrow=True, font=dict(size=10, color='red'))
)
fig.add_annotation(
dict(x=0, y=1.125, xref='x2', yref='y2', text='Model', showarrow=True, font=dict(size=10, color='Blue'))
)
fig.add_annotation(
dict(x=0, y=0.125, xref='x2', yref='y2', text='True activity', showarrow=True, font=dict(size=10, color='green'))
)
fig.show()
