Many people are kind of scared of using programming language. And sure, if you haven’t any experience using these ‘command line’ tools the learning curve may seem steep. And why should you learn a language like Python, if you have a fantastic tool like Alteryx to process your data?

Top 2000 van Radio 2 — 2019
Ieder jaar maak ik op basis van de laatste Top 2000 lijst van Radio 2 een nieuw (aantal) visualisaties.. De lijst zelf is niet heel erg spannend, dus is het interessant om te zien wat je met de data kunt doen…

Top 2000 — 2018
In my annual exercise of visualizing the Dutch Top 2000 I made use of a couple new Tableau tricks, like navigation buttons (a lot of work to create the on alle dashboards, but well worth it) and transparent sheets:
Year-to-date in Tableau
If you want to compare last year to this year ‘to date’, you have to take into account that a leap-year adds 1 extra date to the year – so you can’t just compare the day-of-year from this and last year.
Often this filter is used:
DATEPART('dayofyear',[Date]) <= DATEPART('dayofyear',TODAY())
But this is a better one, since this compares day and month:
YEAR([Date]) >= YEAR(TODAY())-1
AND (MONTH([Date]) < MONTH(TODAY())
OR
(MONTH([Date]) == MONTH(TODAY())
AND DAY([Date]) <= DAY(TODAY())))
If you want to have a ‘year to date’ until today (so today excluded), use this one:
YEAR([Date]) >= YEAR(TODAY()-1)-1
AND (MONTH([Date]) < MONTH(TODAY()-1)
OR
(MONTH([Date]) == MONTH(TODAY()-1)
AND DAY([Date]) <= DAY(TODAY()-1)))
