I wrote a code to show a graph from google finance but i got this error:

ValueError: Missing column provided to 'parse_dates': 'Date'

This was my code:

from bokeh.plotting import Figure, output_file, show

data = pandas.read_csv('http://www.google.com/finance/historical?q=NASDAQ:AAPL&startdate=Jan 01, 2000&output=csv',parse_dates = ["Date"])

f = figure(height = 800,width = 600,x_axis_type = 'datetime')

f.line(data["Date"],data["Close"],color = "orange",alpha = 0.5)
output_file("History.html")
show(f)

What column should I assign to make my code work?

CodePudding user response：

Your html path 'http://www.google.com/finance/historical?q=NASDAQ:AAPL&startdate=Jan 01, 2000&output=csv' does not return a proper csv file and pd.read_csv() can not parse it. Furthermore there is no column named Date.

Internal pd.read_csv() calls pd_read_html() and this returns

This is not what you want. Other posts are using pandas_datareader.
