end = (2014,6,30)

quotes = mpf.quotes_historical_yahoo_ochl('^GDAXI',start, end)
fig, ax=plt.subplots(figsize=(8,5))
fig.subplots_adjust(bottom=0.2)
mpf.candlestick_ochl(ax,quotes,width=0.6,colorup='b',colordown='r')
plt.grid(True)
ax.xaxis_date()
ax.autoscale_view()
plt.setp(plt.gca().get_xticklabels(),rotation=30)

Answer 1

You didn't actually show your plot on screen. When I copy your code and add

plt.show()

at the end of it, it runs just fine.
