Chris, I would strongly suggest you find a different way of
visualising your data than using two overlayed line plots.  This type
of graphic is not an effective way of comparing two time series as it
can be so easily misread and misused.  See

and http://junkcharts.typepad.com/junk_charts/2006/05/the_crossover_l.html
for examples of this.
