Week 37: Recreating Paying the President


This week we’ve partnered with Makeover Monday to examine potential conflict of interest between President Trump’s personal holdings and his campaign staff and government officials using data from Propublica. We’ll also be giving you a few formulas so you can focus on the important parts of the challenge: “stacking” the squares and placing the labels of year, month, and unknown on the “axis”.

1. Create a calculated field called Size. Size will be used to size the squares. The size of the squares represents the overall area of the symbol. There are five different values each representing a different threshold of amount spent at a property.

IF SUM([Amount]) < 1000
ELSEIF SUM([Amount]) <10000
ELSEIF SUM([Amount]) < 100000
ELSEIF SUM([Amount]) < 1000000


  • Dashboard size: 900px x 620px.
  • Background color: #F9F8F7
  • The data has unknown dates. Make all unknown values show up 3 months past the maximum date. If you need help see SPOILERS #1 below for the formula.
  • Create the stacked rectangle plot at the Source level. Use Size to size the boxes. Place a space of 0.01 between each of the squares. Make sure the order of the boxes matches, too. *This is the key challenge this week*
  • Create an “axis” that labels the start of each year as black and abbreviated month labels of April, July, and September, respectively. Also label the unknown values with “Unknown”. See SPOILERS #2: for help with the “axis”. And see SPOILERS #3 for the month label.
  • Color by source_group: Donald J Trump For President: #F7C480, Other: #76B7B2, Taxpayers: #555555
  • Add annotations for when Trump announced candidacy, gets nomination, the election, and inauguration. You’ll want this: โ–ผ
  • Add the annotation around incomplete/missing data.
  • Add the divider and bracket on the dashboard.
  • Match tooltips.

1. For those still learning here is the formula for the spacing the unknown values three months out from the last known month:

IFNULL([Date], DATEADD("month", 3, {MAX([Date])}))

2. For those still learning here is the formula on how to create the faux axis:

IF INDEX() = 1

Using this INDEX() function allows to only show a single mark and not have a bunch of overlapping marks per month.

3. For those still learning here is the formula for creating the month label:

IF DATETRUNC("month", [Date]) != {MIN(DATETRUNC("month", [Date]))}
THEN IF MONTH([Date]) = 4
    THEN "APR"
    ELSEIF MONTH([Date]) = 7
    THEN "JUL"
    ELSEIF MONTH([Date]) = 10
    THEN "OCT"
    ELSE ""
