Hello dear community,
I need your help to solve a small problem I am facing in my internship. I have a YASA 750 electric motor map that I found in a data sheet (attached) and I would like you to extract the iso-efficiency curves (torque, speed and efficiency) and reproduce them in Matlab. Is there a tool that can allow me to do this?

A similar question was answered suggesting importing the image into Matlab and then using ginput to extract coordinates of the axes and desired curve in the picture reference coordinate system. The last step involving "correspondence matching" is a bit vague.
