I don't know whether it is ther perfect way but I did something similiar
with using a factor. So you could use factors from 1:(number of days)
and the dates as factor labels. But maybe there is a better way.


ps I would be interested in "truth" plotting if someone has a function
it could substitute parts of my reserach ;-)
