In the past weeks, I had the immense honor to collaborate with Steve Wexler on revisiting his famous Churn Dashboard from the Big Book of Dashboards. The #BBOD was one of the first books that came across my way when I discovered dataviz and Tableau as a topic about two years ago. Continue reading “Polygon Waterfall Charts”
Ok, this is probably not a big thing, but I have been thinking about it for quite a while now: How can I encode change in line charts accurately?
Wait: Encoding change in line charts?
Change is of course already encoded in line charts. For example, when we look at Superstore sales by month we can see the change: when the line goes down, we have a negative change compared to the previous month and when the line goes up, we have a positive change.
Today my students and I practiced a waterfall chart – a chart type you just have to know when you want become an accountant 🙂
While practicing I brought up the idea of a connected waterfall chart, something I did for the first time in a #makeovermonday some weeks ago (click for the interactive version on Tableau Public). Continue reading “Connected Waterfall Charts”
This week I had a lot of fun recreating Lorna Eden’s #WorkoutWednesday2019 challenge. One key element was to implement a custom sort control (click to play with the interactive version on Tableau Public): Continue reading “Custom Sort Control in Tableau”
a collaborative blog by Ken Flerlage and Klaus Schulte
Last week at work I (Klaus) puzzled my head over an interesting question. I was looking at production orders and production dates and had to calculate differences between production dates:
- If a production order has consecutive production days (the datediff between the days is 1) then the machine only has to be equipped once.
- If the datediff between two production days is >1, the machine has to be equipped on each production date.
The Table Calculation-Approach
When I was reading a news website earlier today I had this nice user experience when I was hovering this chart:
At #TC18, right before #IronViz, I had a nice conversation with Zen Master Ann Jackson about table calculations in Tableau that can be summarized like this:
Do you want to learn more about “everything is a scatterplot” and the “multiple-layer-technique”?
Then rebuild my kinked bar chart!
