Summary: The bins...A bug in Tableau – Broken bin: <br />Summary: The bins may break when upgrading to a newer version of Tableau.<br />Fix: Recreate the bin and replace the old one.<br /><br />Details:<br />Source workbook file = v 10.4 (which is what is used in this post as of 2020-04-26 - Your posts are FANTASTIC!! THANK YOU!!)<br />Tableau version = 2020.1.20.0326.1623 – 64-bit Professional Edition<br />Actions:<br />1: Download the workbook in this post (version 10.4)<br />2: Open the workbook with Tableau v2020.1.20.0326.1623 – 64-bit Professional Edition<br />3: Unhide the Dashboards in the Story<br />4: Unhide the worksheets in Dashboard #3<br />5: Look at worksheet ‘S’, you are going to recreate this using a NEW worksheet. Do not duplicate any existing worksheets in the workbook. Click the ‘new worksheet’ icon on the far right.<br />6: Drag ‘Range (bin)’ to details card<br />7: Drag ‘x’ to the Columns shelf<br />8: Drag ‘y’ to the Rows shelf<br />9: Set ‘x’ and ‘y’ to ‘Compute using Range (bin)’<br />10: What you should see is a circle of dots… but it will not happen…<br />If you go to the menu item ‘Worksheet’ and ‘Describe Sheet’ you will see that ‘Range (bin)’ only has two members: ‘0 ;60’. This is the problem<br />To fix this:<br />11: Right click the measure:‘Range’ and create a new ‘Range (bin) 2’ Dimension.<br />12: Replace the 'Range (bin)' that is currently on the ‘Details’ card with the one you just created. You will have to fix ‘x’ & ‘y’.<br />That should get the circle to work.<br />I am now going to find some Band-Aids to put on my forehead and buy a new keyboard.<br />BrianRLeBlanchttps://www.blogger.com/profile/03184820879067142641noreply@blogger.comtag:blogger.com,1999:blog-3178813192704651028.post-59287286281418146492020-04-15T09:22:26.364-04:002020-04-15T09:22:26.364-04:00Our pleasure!Our pleasure!Ken Flerlagehttps://www.blogger.com/profile/03698843288892226027noreply@blogger.comtag:blogger.com,1999:blog-3178813192704651028.post-14041046779871508362020-04-15T06:56:36.703-04:002020-04-15T06:56:36.703-04:00Hi Kevin & Ken!

I have a question: How would I do the range for t for -8:8 as shown in the " And here are a two more, which I found on the Life Through a Mathematician’s Eyes blog." - I tried everything but I probably missed the obvious - I also tried doing : ([Index]-1)*(-8*(22/7)/5000) and ([Index]-1)*(8*(22/7)/5000) and then tried a Dual Axis - but the shape is not coming like yours - apologies for some obvious ignorance.

I found it quite insightful, to understand how these interesting custom shapes are created. Still don't quite understand why Tableau was creating the shapes using line and polygon in the beginning before t was restricted [0,2π]. Also, i was following your post to create the circle and noticed that i couldn't get the circle to close after making t =([Index]-1)*0.104719755, unless I increased the max range from 60 to 61. Not sure if it was implied in the post or I did something wrong. Anyways, it was a very insightful post and i love to look at the old math and see how they could be used in art and tableau! thanks again for opening my eyes!Unknownhttps://www.blogger.com/profile/13419585640564438162noreply@blogger.comtag:blogger.com,1999:blog-3178813192704651028.post-38376733604930879072017-12-01T21:42:46.657-05:002017-12-01T21:42:46.657-05:00BTW.

I've gotten in the habit of downloading public vizzes and exploring them over the last few year and have found the great vizzes always have a bit of complex math driving the view. It has often seemed that the math is what is keeping me from moving my Tableau game to the next level. This will help a great deal.
