info needed about plugins

[Vishwanath Somashekar]

Hi,
I was wondering if there is any plugin for say plotting intensity
profiles along various lines from various images in the same window.
Right now, if i draw a line in the window and hit ctrl+k, there is a
intensity profile, but i can put another profile in the same graph.
Essentially, I am looking for a plugin which does job of excel..Hope
to hear from you folks soon..

thanks,
Vishwa
