Graph2Data: Graph to Data Python Implementation

In a discussion with Engr. Azhar Dilshad on his PhD research work, I came up with the idea to generate data from real-time visual display. A subset of idea is implemented in Python. The code below is fairly simple and self explanatory.

Input Image: The labels show the area of the image to process. They are (120,80) and (615,375).

The Code:

Output From Extracted Data: 

A number of enhancements to the code are possible. Few, I am interested in are: x and y axis labels, and implementation on real time image data frames.
