Generate Code for MATLAB using ImageJ

Hopefully I can explain this properly --

I have a JPEG file of a graph. On this graph are 10+ lines/curves. I don't have the data that was used to produced these lines/curves, but I want to create code for the graph in MATLAB.

My question: Is there a way I can use ImageJ and MATLAB together to both measure the existing JPEG image and then extrapolate MATLAB code from that? In the end, I would like the user to access a drop-down menu (or slider, doesn't matter) to view 1 or all lines with MATLAB.

Is this possible?

Edit: If this is possible with just MATLAB, that is fine, too!
