For Part 2, I'd love to see how to user the Window function to create a bar chart that shows sales per month for a selected year but has a reference line which shows the average sales per month across multiple years. This would allow the user to see, for example, how sales for January 2022 compares to average sales for January from 2017 to 2022.

Great video! You saved me hours trying to figure this out. Unrelated question -- what tool are you using to annotate your screen with boxes, arrows, etc. while recording?

Hi Tim: This was excellent. Like others, I'm eagerly awaiting Part 2. Any update on when it might be out?

Thanks for all your efforts!!! 💯👍

Hi Tim - what is the software/tool that you use for highlighting things with color and arrows while you present on your screen? I'm going to explain Table Calcs to users next week, and that would be super handy ! Your videos are awesome. Thanks :)

That's the class I needed! You read my mind!

PS: if you hold click and move the cursor of the mouse along the cells, you can select a range of cells (it is hard to explain this in words, but I tried, rsrs)

Very nice explanation and great video! As you mentioned at the end of the video, I would love to see part 2 go through some contrasting real-world examples of when you would want to use window functions.

hazelyip

Absolutely amazing presentation and explanation. Can't wait to spend the next two months trying to cram this tool into every project I get assigned!

I am preparing for the Data Analyst cert. and I can anticipate them just showing me a formula and asking for the expected value. It is one thing if you have the tool open and can play around, but another when you have to calc this in your head. OK maybe if the examples are as simple as shown here, but I suspect the worst of the Tableau test writers. Do you have any guidance regarding the level of familiarity one needs with WINDOW to sit this exam?

I suppose that advocates of Tableau would champion this as being flexible, but to me this is not user friendly and is confusing.
That said, your explanation is solid - thank you TT.
