Hey!
I have this .png image of some graphs and I want to store the data of all the info found in this type of graph (turbine graphs), in different vectors. Can anyone help?

For instante, in this case identify the best efficiency point and its efficiency (94.12), and the Q, H and Power for that point (6.45 m3/s, 24.05m and aprox. 1.4MW)

Try this file form file exchange: https://www.mathworks.com/matlabcentral/fileexchange/7173-grabit
Note that it is a tedious job and it is on our patience.

I've already seen that, but with Grabit you have to do it yourself for every image (calibrate the axes, etc). Isn't there any code to do that automatically?
