Please disregard, i finally solved my problem using IndexLocator:
# datetime variable x is in 15 min intervals, 6 1/2 hours in trading day
# results in 26 data points per day, so:
days = IndexLocator(26, 1)
hours = IndexLocator(4, 1)
ax = subplot(111)
plot(datesindex, y)
ax.xaxis.set_major_locator(days)
ax.xaxis.set_major_formatter(IndexDateFormatter(x, '%Y-%m-%d %H:%M:%S'))
ax.xaxis.set_minor_locator(hours)
ax.xaxis.set_minor_formatter(IndexDateFormatter(x, 'Y-%m-%d %H:%M:%S'))
Thanks to all who have help me with previous issues. :)
