Problem with finance_demo.py

The following code (is a simple modification of
finance_demo.py) produces a stock chart. SOme of the
lines are thicker than the others. All the lines
should have the same width.

import datetime
from pylab import *
from matplotlib.finance import
quotes_historical_yahoo, plot_day_summary2

import time

axesBG = '#f6f6f6'
figBG = 'w'
date1 = datetime.date( 2002, 2, 1)
date2 = datetime.date( 2004, 12, 12 )

quotes = quotes_historical_yahoo(
    'INTC', date1, date2)

quotetime, open, close, high, low, volume =
zip(*quotes)
numPriceBars = 261

ax = subplot(111)
plot_day_summary2(ax,
open[0:260],close[0:260],high[0:260],low[0:260])
set(ax.get_xticklabels(), 'rotation', 45,
'horizontalalignment', 'right', fontsize=7)

show()
