This is wonderful video, thank you so much for this. But doesnt that hidden sheet create problem during tab navigation?. I am trying to build an accesible Dashboard and I am integrating Tab focus as a part of it. Leaving the "Hide sheet" will make the Tab to focus on it. Is there a workaround we can do to not include "Hide sheet". I know it is needed to include all values in extension, but if there is a workaround it will be helpful for my Dashboard design.

Thank you 🦋. I have a question. (answered my own question, i have to use bars instead of area chart)
Can you guide me on how to set up (if possible) a Tableau visualization where a single record contributes to multiple categories in a bar chart? For instance, I want to count Record X in both the 'Red' and 'Yellow' categories within the same chart, based on different criteria. If I had Record X1 and Record X2, this would be easy. I think that a dual-axis chart could be used somehow, but that is more complicated than I want it to be.
Example Data:
Record X, task attempted, status success
Record Y, task attempted, status failed
Chart Funnel:
Top of Funnel is Red for all tasks attempted
Next section is Yellow for all tasks that succeeded
When i try to do this with measures, the whole chart turns blue and i can't see different colors for different sections of the funnel, even though the color legend does show multiple colors.
I think the issue is that a single record can only be one color in any one chart?
