我正在嘗試?yán)L制一個(gè) 3 子圖 PlotLy 圖。從上到下：燭臺(tái)、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(cuò)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(dú)繪制燭臺(tái)圖表并且效果很好所以我很漂亮它與行和列部分有關(guān)，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(yīng)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)
