Introduction
Have I ever talked about how much I love table calcs? They are super powerful and often more performant than the often overused LOD expression. So that’s what we’re going to practice this week.
Can you create a control chart only using table calcs?
Requirements
- 1 sheet
- create a trend chart with dynamic user-selection to show the last n weeks
- create a reference band of showing +1 and -1 standard deviation of the entire dataset
- the reference band should NOT change with Date filtering but will for other dimension filters
- create a median reference line of the entire dataset
- the reference line should NOT change with Date filtering but will for other dimension filters
- add dots for each value on the line and color based on performance relative to the reference band
Dataset
