I only started using matplolib a few days ago, but I think I know how
to do what you want:
----------------------------------------
import matplotlib.dates as mdates # To read timestamps
...
xAxisTimeFormat = '%a\n%H:%M' # Format of time stamps on x-axis
hourLocator = mdates.HourLocator(interval=5) # Every 5 hours
minuteLocator = mdates.MinuteLocator(interval=30) # Every half hour
...
ax.xaxis.set_major_locator(hourLocator) # Set major tick marks
ax.xaxis.set_minor_locator(minuteLocator) # Set minor tick marks
ax.xaxis.set_major_formatter(mdates.DateFormatter(xAxisTimeFormat)) #
Format x-axis labels
----------------------------------------
I have a full example of plots that have a point every minute over the
course of days:
