PNGTitle not appearing on the graphs

I want titles to appear on my graphs. for that i have added the foll. line
to the router config file.
PNGTitle[routername.interfacename]: Graph title
But i cannot see this title on the graphs generated. 

Can anyone please tell me what needs to be done to generate the titles?

Thanks
Nisha
