Tenzin - this is a big ask. What have you tried so far?

How'd you get the image into the axes in the first place? You should already have the data if you plotted it, so you don't need to pull from the axes.

As for OCR, consider this example and this Answer.

If you want to pull it from the axes (and sometimes that is easier than passing an image along through deeply nested calls), you can use getimage()

imageInAxes = getimage(axesHandle);
