It is not mandatory, nor do I have any way to enforce it, but for the sake of our community, please do this once you get the answer you want if you started the thread.
- collect your thoughts and try simply your solution from answer(ie. only graph screen cap that contains necessary info, get rid of unnecessary prints, comment important nodes)
- edit your FIRST post and have a section that explain the answer, so anyone in the future that might ask this question get to see the answer in first post.
- if you have more time, head toward answer hub and see if there are similar question asked. If none, post your question and answer there, if there are, try to help them out and leave a link to your thread.
