我正在尝试在python中绘制蜡烛棒图。这是我的代码
from pandas_datareader import data as pdr
import plotly.plotly as py
import plotly.graph_objs as go
import fix_yahoo_finance as yf
yf.pdr_override()
mcd = pdr.get_data_yahoo("MCD", start="2004-01-01", end="2005-07-31")
mcd_candle = go.Candlestick(x=mcd.index,open=mcd.Open,high=mcd.High,low=mcd.Low,close=mcd.Close)
data = [mcd_candle]
py.iplot(data, filename='Candle Stick')
这是我得到的错误
PlotlyError: Because you didn't supply a 'file_id' in the call, we're assuming you're trying to snag a figure from a url. You supplied the url, '', we expected it to start with 'https://plot.ly'.
我知道如何绘制蜡烛图表吗？
答案 0 :(得分：4)
问题必定是因为您没有提供mapfn newblk: copy/deep myblk :reverse
和username来自api key链接的内容。如果您想使用https://plot.ly/settings/api来创建此图表。首先创建一个帐户，然后获取plotly online和username并将其插入下面的代码中。
api key使用from pandas_datareader import data as pdr
import plotly.plotly as py
import plotly.graph_objs as go
import fix_yahoo_finance as yf
py.sign_in('<<username here>>', '<<api key here>>')
yf.pdr_override()
mcd = pdr.get_data_yahoo("MCD", start="2004-01-01", end="2005-07-31")
mcd_candle = go.Candlestick(x=mcd.index,open=mcd.Open,high=mcd.High,low=mcd.Low,close=mcd.Close)
data = [mcd_candle]
py.iplot(data, filename='Candle Stick')
还有另一种选择，不需要所有这些程序，请在下面的实施代码中找到。
plotly offline如果这些库不存在，请确保使用from pandas_datareader import data as pdr
import plotly.offline as py_offline
import plotly.graph_objs as go
import fix_yahoo_finance as yf
py_offline.init_notebook_mode()
yf.pdr_override()
mcd = pdr.get_data_yahoo("MCD", start="2004-01-01", end="2005-07-31")
mcd_candle = go.Candlestick(x=mcd.index,open=mcd.Open,high=mcd.High,low=mcd.Low,close=mcd.Close)
data = [mcd_candle]
py_offline.iplot(data, filename='Candle Stick')
#for Spyder plotting use the below line instead
#py_offline.plot(data, filename='Candle Stick')
安装库pandas_datareader和fix_yahoo_finance！
