Hey Adam,
I think I have this fixed in svn -- also, I rewrote your example to
use csv2rec (which returns record arrays). Thought you might be
interested:
import matplotlib.mlab as mlab
import matplotlib.pyplot as plt
import matplotlib.dates as mdates
import matplotlib.cbook as cbook
r1 = mlab.csv2rec('test1.dat', names='date,value', delimiter=' ',
converterd={'date':cbook.todate('%Y%m%d')})
r2 = mlab.csv2rec('test2.dat', names='date,value', delimiter=' ',
converterd={'date':cbook.todate('%Y%m%d')})
print 'dtype', r1.dtype
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax2 = ax1.twinx()
# produce plot
line1, = ax1.plot(r1.date, r1.value, 'bo-')
line2, = ax2.plot(r2.date, r2.value, 'bo-')
# set up axes
ax1.xaxis.set_major_locator(mdates.DayLocator(range(0, 31, 2)))
ax1.xaxis.set_minor_locator(mdates.DayLocator(range(0, 31, 1)))
ax1.xaxis.set_major_formatter(mdates.DateFormatter('%Y/%m/%d'))
plt.show()
