I have used chart.js for drawing the graph and the following plugins I have used.

I have implemented a sample code and getting the graph as expected . But the same code integrated with my project,I am getting the following error

Uncaught TypeError: Cannot read property 'unobtrusive' of undefined
at Object.jQuery.validator.unobtrusive.parse

When I commented the first 4 lines that error disappears .But I need those plugins to meet my requirement.
Could you please help me?
This is very important for me as I have to demonstrate this tomorrow.

I have attached the existing plug-ins in the project.
