I don't think the figure came out the way you intended. One of the pendulum cords is too far to the left, and supposedly they are separated by a spring.
A Java video simulation of what you want can be found at http://www.maths.surrey.ac.uk/explore/michaelspages/Coupled.htm
Choose different values for the masses or lengths if you want to see interesting behavior, with major motion going back and forth from one to the other.
can you help find a online video of a double pendulum where it looks like this:
