Just a random thought, though I don't have experience with the module
pylab and the function titleList, it sounds like you need to
initialize the titleList inside the same plot_plot() function, rather
than from outside.  I would say try:
>ax.plot_date(id_dates,yaxes_values[count],fmt='o-',label=titleList[count])
>                 pylab.xlabel('Time Stamp')
>                 pylab.ylabel('Values')
>titleList[count]=''  #or [] if it is a multivalued variable.

Hope it helps,
