[Forward: I asked ChatGPT o1-mini who then wrote this. Hope it helps. All the credit and the blame go to ChatGPT.

I went over the plan and it looked decent. Whether it can be done in 30 days or not, it depends on the person and the time he spends on it.

#TweakThursday: From time to time I tweak someone else's public viz and try to make it better to my subjective view.

How does one use horizontal bars and vertical bars? How to order time-based multiples in a trellis chart?

Here are my own rules of thumb:
  • Vertical bars are for time-based trends.
  • Horizontal bars are for categorical comparison.
  • Always place the latest cell in a time-based trellis at the top-left corner where the focus is.
I found that Professor Klaus Schulte's recent MakeoverMonday viz submission is quite interesting. I just tweaked it a bit according to the above rules. Hope it makes the viz a bit more interesting.

Here is my resulting viz. Feel free to download it and explore.

Note that the vertical axis is the bins for the histogram. We easily see France is placed in higher bins than the other 3 highlighted countries recently. Since the most recent is more interesting than the past, placing the the latest cells at the top left corner makes it easier to check.
Had a few exchanges with Klaus in Twitter about my reasoning behind the edit.

Just came back from Tableau Conference 2022 at Las Vegas. What an exciting event! The most exciting thing is reuniting with old friends and meeting with the datafam people known online for years.

Attended first time the Tableau Visionary summit.
A little enhancement in the formula editor can make a big difference for whose who create formula all the time in Tableau. Here are my wishes for a future editor. 

Highlighting Syntax Words

Currently a formula in Tableau can look plain and a bit uninspiring.
