Excel using COUNTIFS Function to create a Punchcard -

-



in data source have column contains dates of occurrences , column contains hour of same occurrences.

with this, goal obtain punchcard plot (maybe bubble chart appropriate)

the intermediate structure has weekday(sunday-saturday) rows (a2:a8), , hours (8-22) columns (b1:p1), each column must have occurrence count week day in hour.

with said, tried use countifs function, using following approach, cell b2:

=countifs(weekday(rawdata!t2:t9852;1);a2;hour(rawdata!u2:u9852);b1)

however, excel not computing value, finding problem on formula, having tried using insert formula option.

place following in b2

=sumproduct((weekday($t$2:$t$8,1)=weekday($a2,1))*(hour($u$2:$u$8)=hour(b$1)))

you need convert , match ; on system

  1. in range a2:a8 enter known date monday such 2017/08/20. select a2:a8 , apply custom formatting number format , set ddd. display day of week in text keep value in cell number.
  2. adjust ranges suit data.
  3. copy formula fill in table.
