I believe he utilized a list of already generated points on the number line for his work, then used T values to draw the circles. I am not yet there in Tableau, but can most of the work in Excel. I will be honest and tell you that I had not even considered obtaining a list of points on the number line so in my mind, I had to calculate them myself. In fact, most of the work in this spreadsheet was simply to determine the list of points to be used. (Each row that contains a start point is one that determines a point on the number line. Each row without a start point is simply used to draw the line). Recaman's Sequence says the move increases by one each time, you must move backward if you can (if not, you would move forward) and you cannot use the same number twice. The "Already Used" field is used to determine if the newly generated point (Initial Result - which was a move backward per the sequence) on the number line had been used before (Start Point). If it had not been used previously, then it would become the "Final Result". If it was used previously, then the move would go forward instead of backward and a new Final Result would be calculated. I'd be happy to share the spreadsheet with you and walk through it with you if you like.

That was a mouthful...if you don't follow me, I'd suggest reading my blog post on parametric equations: http://www.kenflerlage.com/2017/11/beyond-show-me-part-3-parametric.html.

Pertaining to this viz, I have a question regarding the T arc in Ken's and Already used in Kevin's solution. How did you guys come up with this equation?Unknownhttps://www.blogger.com/profile/07651042755923654188noreply@blogger.com
