plotly基于dataframe数据绘制股票K线图并过滤非交易时间

 #ohlc过滤非交易时间；

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\'])

trace = go.Ohlc(
    x=df.index,
    open=df.open,
    high=df.high,
    low=df.low,
    close=df.close,
)

# fig[\'data\'] = [trace]
fig.add_trace(trace)

fig[\'layout\'].update(
    xaxis=go.XAxis(
        autorange=True,
        mirror=\'all\',
        gridcolor=\'rgb(180, 180, 180)\',
