You can use a numpy masked array, and mask the values that you don't want to plot. Or you can use a normal numpy array and set the missing values to numpy.nan. (There seem to be a few side cases where the second option doesn't do what you would expect in 0.91.2, but AFAIK it works in recent revisions of the SVN trunk.)
In either case, you will still need to assign dates to correspond to those "missing" values. See masked_demo.py for an example (which doesn't use dates, but the concepts are the same).
