Hello, I love your visualization schemes. I did try it out. But with no success. I don't get any error message, just a blank white screen area. My Tableau Version is: 2020.4.4 64 bit Windows 10 OS Here are my steps:

On the next two wizard steps, I just accept the defaults. this is what I get:

Can you please confirm that you are following the required data structure documented in the readme file? For example, in your screen shot, I do not see a root node with a null parent.

Select a sheet that is on your dashboard and contains you hierarchy data. Here is an example table of what is required for hierarchy data for this extension to work correctly.

Parent Node	Child Node	Some Value	Color By	Other Stuff(n)
null	rootNode	100	black	categoryValue
rootNode	child1	20	blue	categoryValue2
rootNode	child2	20	green	categoryValue1
child1	child3	100	blue	categoryValue2
child1	child4	100	blue	categoryValue2
child2	child5	100	green	categoryValue1

Please take note: that there must be one, and only one record which has a null parent (even if it is fake), this is the root node of your hierarchy from which all things are made, if you do not provide a single root node (in the souce data sheet), the extension will crash.

I am having the same issue today. I tried to follow the instructions in the Tableau extension and use the most basic settings and nothing renders. My data is literally Parent Node Child Node null Company A Company A Company B Company A Company C Company A Company D

Hi @Calantha21 ! I was able to render the extension without issue using your data set. You can see the workbook here on Tableau Public for reference: https://public.tableau.com/views/SemioticSimpleExample/Dashboard1?:language=en-US&:display_count=n&:origin=viz_share_link

If you are still getting issues, please confirm which Version of Tableau you are using if you don't mind. Thanks!

Hi Chris,

Thanks for the quick reply. Your sheet one looks exactly like mine. I did some more troubleshooting and here's what I have so far. I tried suspending my laptop VPN (I thought the corporate firewall might be blocking) - no luck.

I'm using the version of Semiotic Hierarchy that is provided by the Extension Gallery now in version 2021.1.2. I also re-installed 2020.2 to see if that fixed it and downloaded the trex file from the public website to see if that fixed it.

So far, I still just get a blank screen. I've attached the screen shots - this is in 2021.1.2.

So...I tracked down the culprit...the "Null" was not actually null...it was the word "Null" Everything seems to be working now. Sorry for all the bother.

demartsc commented 3 years ago

Aww yes! The null value cannot be the strong null… the data prep stuff in the extension was probably failing due to not being able to find the root parent. Glad you got it sorted!

Closing this issue.
