Hi, the best to do if you are using MATLAB is to save the plots as .fig files in addition to .png or .pdf files. By doing so, all the data are saved.

Hi saurav,

you have to download a software called

Graph Data Extractor

From this software you can get date from jpeg image files

A simple application for extracting numerical data from published images which graphically represent data sets to which you do not have access.
