Topic: graph program -jpg input (?)

Hallo everyone!
Here is the problem: I have plots for size distribution as file.jpg and I am looking for a programm that I can use these files as inputs in order to find peaks, curve's width and other things that I need in order to compare these theoritical graphs to my experimental graphs. Is there any program that I can use?
I attach file.jpg for you in order to help you understand.thank you a lot!

Re: graph program -jpg input (?)

It looks like you forgot to attach the file.

Though Graph can export as jpg it cannot import anything from a jpg file.
