ValueError: The data property of a figure may only be assigned a list or tuple that contains a permutation of a subset of itself.
问题:
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)',
showline=True, # 画出 X 轴那条线
showgrid=True,
tickangle=-60,
categoryorder="category ascending",
type='category'),
yaxis=go.YAxis(
autorange=True,
gridcolor='rgb(180, 180, 180)',
),
)
pyplt(fig, filename=r'tmp/ohlc_filter_time.html')
解决:
# fig.add_trace(trace)
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)',
showline=True, # 画出 X 轴那条线
showgrid=True,
tickangle=-60,
categoryorder="category ascending",
type='category'),
yaxis=go.YAxis(
autorange=True,
gridcolor='rgb(180, 180, 180)',
),
)
pyplt(fig, filename=r'tmp/ohlc_filter_time.html')
