See this file exchange: https://in.mathworks.com/matlabcentral/fileexchange/7173-grabit
If you have .fig,,,you can get the handles of the figure and the handles have XData and YData.

https://www.mathworks.com/matlabcentral/answers/100687-how-do-i-extract-data-from-matlab-figures#answer_110036 - save your graph as .fig instead of .jpg ("No appropriate method, property, or field 'ZData' for class 'matlab.graphics.primitive.Image'. )
