Attached an image containing a graph. I wish to know that is there a way that MATLAB reads the graph automatically?

1. What do you want as a result? Sets of point or Equation of Curve?
2. Is scale fixed? Or you want user to input scale after image reading?

There are a number of tools in the File Exchange for digitizing graphs; see http://www.mathworks.com/matlabcentral/fileexchange/?term=digitize&sort=ratings_desc
I do not think any of them are fully automated though; that would require a lot of OCR work.
