import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt
import matplotlib.finance as mpf

start = (2014, 5, 1)
end = (2014, 6, 30)
quotes = mpf.quotes_historical_yahoo_ohlc(‘^GDAXI’, start, end)
#quotes = mpf.quotes_historical_yahoo(‘^GDAXI’, start, end)

fig, ax = plt.subplots(figsize=(8, 5))

print “Hello”
#use Line2d
#mpf.plot_day_summary_oclh(ax, quotes, ticksize=3, colorup=’k’, colordown=’r’)#
mpf.candlestick_ohlc(ax, quotes, width=0.6, colorup=’b’, colordown=’r’)
#mpf.candlestick(ax, quotes, width=0.6, colorup=’b’, colordown=’r’)
# dates on the x-axis

plt.setp(plt.gca().get_xticklabels(), rotation=30)
#raw_input(“Press Enter to continue…”)
print “bye”
