Question

这是从散景文档中选取的示例。它显示属性错误。我在anaconda环境中使用ipython。

import pandas as pd
from bokeh.charts import TimeSeries, output_file, show

AAPL = pd.read_csv(
        "http://ichart.yahoo.com/table.csv?s=AAPL&a=0&b=1&c=2000&d=0&e=1&f=2010",
        parse_dates=['Date'])

output_file("timeseries.html")

data = dict(AAPL=AAPL['Adj Close'], Date=AAPL['Date'])

p = TimeSeries(data, index='Date', title="APPL", ylabel='Stock Prices')

show(p)


AttributeError                            Traceback (most recent call last)

Answer 1

而不是使用属性索引，设置x =＆＃39;日期＆＃39;。

p = TimeSeries(data, x ='Date', title="APPL", ylabel='Stock Prices')

Answer 2

检查您使用的是哪个版本，如果您使用的是0.11.1，则可以使用 http://bokeh.pydata.org/en/0.11.1/docs/user_guide/plotting.html也是这样做的。

属性错误：TimeSeries Bokeh Library
