// js for patch panel app custom view
/**
IMPORTANT CHANGES THAT MUST BE MADE BEFORE SUBMITTING

-Graph is not being updated with packet counters. The counters is only set to 0.
 This is a New bug, after individual buttons were removed.
-HTML Page is not being resized depending on the the size of the screen.
-Must Enable Scrolling
-Can Remove Redundant Code and create one json file, instead of multiple.
-Add comments and work on the code formatting.

Due to a paucity of time, I couldn't work on some of these important changes.
The first bug is very important to correct and the code should not be in the ONOS
codebase without the change.

Feel free to contact me for any issues.
