Ah, you wanna plot your data year by year, right ? In that case, you don't really need the dates anymore, and I suggest you plot the .series attribute instead (that's the masked array that stores only the data. It has faster access than the whole timeseries because you don't have to access the dates anymore). 
Now, your problem simplifies into : how to plot multiple rows at once. You can loop on the rows, or check in matplotlib if there's not another trick (try a LineCollection if you don't need different colors for different years/rows)
