to read in data set clipboard do

from pandas import read_clipboard matplotlib.dates import date2num names = ['date', 'open', 'close', 'high', 'low'] df = read_clipboard(sep=',', names=names, parse_dates=['date']) df['d'] = df.date.map(date2num)

the top-level pandas.read_csv function works pandas.read_clipboard, if have data sitting in csv or other type of character-delimited file.

now on plotting:

from matplotlib.pyplot import subplots, draw matplotlib.finance import candlestick  seconds_per_day = 60 * 60 * 24 fig, ax = subplots() candlestick(ax, df[['d', 'open', 'close', 'high', 'low']].values, width=1.0 / seconds_per_day) ax.xaxis_date() draw()

gives
