It doesn't look like you've replicated the sample exactly. I'd suggest you run through the steps again and make sure you re-create the Table Calculations in the same way. I'd say something else is missing in your work as well, so just be sure to doublecheck it.
The easiest thing here would be to create a datasource with the same structure as Bora's example and use the 'replace data source' option.

Philip George Jun 17, 2016 9:26 AM (in response to Tom W)Hi Tom,
Thanks for the reply.
I am trying to understand the polygon building logic used by Bora for creating the radial charts instead of just imitating the work.
if anyone can give some source to refer the concepts then it will be helpful.
Regards,
Philip

I won't attempt to explain the specific logic Bora is using, I won't be able to do it justice.
Personally I'd replicate a new sample then start reverse engineering each of the calculations and table calcs. I see Bora has put a bunch of comments in his X and Y calculations to try help explain the math behind it. To get the level of detail you're after though, you might be best to reach out to Bora.
