plotly基于dataframe数据绘制股票K线图并添加技术指标

# 添加均线数据；

import plotly as py  # 导入plotly库并命名为py
import plotly.graph_objs as go
import pandas as pd

fig = go.Figure()

# -------------pre def
pyplt = py.offline.plot

df = pd.read_csv(r\'dat/appl.csv\', index_col=[\'date\'], parse_dates=[\'date\'])
df[\'avg_5\'] = df[\'close\'].rolling(5).mean()

# K线图
trace = go.Candlestick(
    x=df.index,
    open=df.open,
    high=df.high,
    low=df.low,
    close=df.close,
)


# 5日均线拟合直线
add_line = go.Scatter(
         x=df.index,
         y=df.avg_5,
         name= \'5日均线\',
