我正在嘗試繪制一個 3 子圖 PlotLy 圖。從上到下：燭臺、法線圖、法線圖。這是我的代碼：def chart_strategy(df): # Initialize figure with subplots fig = make_subplots(rows=3, cols=1) fig.add_trace(go.Figure( data = [go.Candlestick( x = df.index, open = df['Open'], close = df['Close'], low = df['Low'], high = df['High'])]), row = 1, col = 1) fig.add_trace(go.Scatter(x = df.index, y = df['System Quality Number']), row = 2, col = 1) fig.add_trace(go.Scatter(x = df.index, y = df['Action']), row = 3, col =1) return fig我收到以下錯誤：ValueError: Invalid element(s) received for the 'data' property of Invalid elements include: [Figure({'data': [{'close': array([120.88, 120.93, 120.72, ..., 116.23, 115.78, 115.63]), 'high': array([121.31, 121.2 , 121.11, ..., 116.86, 116.43, 115.73]), 'low': array([120.8 , 120.79, 120.48, ..., 115.94, 115.68, 115.32]), 'open': array([121. , 120.81, 120.92, ..., 116.36, 116.23, 115.71]), 'type': 'candlestick', 'x': array([datetime.datetime(2019, 7, 19, 0, 0), datetime.datetime(2019, 7, 22, 0, 0), datetime.datetime(2019, 7, 23, 0, 0), ..., datetime.datetime(2020, 5, 12, 0, 0), datetime.datetime(2020, 5, 13, 0, 0), datetime.datetime(2020, 5, 14, 0, 0)], dtype=object)}],'layout': {'template': '...'}})]我嘗試只單獨繪制燭臺圖表并且效果很好所以我很漂亮它與行和列部分有關，只是不確定接下來要搜索什么。我使用以下資源編寫此代碼： https ://plotly.com/python/table-subplots/ https://plotly.com/python/candlestick-charts/

問題是您如何添加第一條軌跡。您正在使用：
fig.add_trace(go.Figure( data = [go.Candlestick( x = df.index,...
但它應該是：
fig.add_trace(go.Candlestick(x = df.index,...
import numpy as np
import pandas as pd
import plotly.graph_objects as go
from plotly.subplots import make_subplots
N=14
df = pd.DataFrame({'Open': np.random.randint(1,29,N),
'Close': np.random.randint(1,29,N),
'Low': np.random.randint(1,29,N),
'High': np.random.randint(1,29,N),
'Action': np.random.choice(['sell', 'buy'],N),
'System Quality Number': np.random.randint(1,29,N)})
def chart_strategy(df):
fig = make_subplots(rows=3, cols=1)
fig.add_trace(go.Candlestick(x = df.index,
open = df['Open'],
close = df['Close'],
low = df['Low'],
high = df['High']),
row = 1, col = 1)
fig.add_trace(go.Scatter(x = df.index, y = df['System Quality Number']),
row = 2, col = 1)
fig.add_trace(go.Scatter(x = df.index, y = df['Action']), row = 3, col =1)
fig.update_xaxes(row=1, col=1, rangeslider_thickness=0.05)
fig.update_layout(width=900, height=900)
return fig
chart_strategy(df)
