How to hang a swing on an angled tree branch and have it swing straight

So far I have set this up with one rope attaching at the bottom of the branch on the higher side (left side of photo) and attaching the rope so it swings from the side of the branch on the lower side (right side of photo). I tied them the same way but through the lower side over the branch. This is almost but not quite adequate to make the it swing straight. Any thoughts out there? I of course could build a frame or find a better brach but was hoping for an elegant solution using the rope only.
 


I ended up getting this Bucket Toddler Swing as it was the cheapest decent looking one on line at the time. Pretty happy with it. Very solidly built.

I won't go into the how details because you can work it out from her post. If you want to use the template I have posted here

Since it is a rare statistics related post I will give props to the medical stats book I am using these days. Medical Statistics: A Textbook for the Health Sciences
