Secondary structure content (%) vs time sounds more like a single plot of the fraction of residues (%) of residues at each time point that are not in a 'coil' state.

That's just the ss.xpm file.  The scount.xvg has a time series of the number of 
residues in each type of secondary structure over time.  To the OP's question, 
it is not a percentage, it is the number of residues, from which computing 
percentage is trivial based on the number of total residues.
