Time-series option to show X-over-X (e.g. X=Month) Growth Rate, Y-X Moving Average (e.g. y=30, X=day)

[shane-kercheval]

• Year-over-Year (implemented; checkbox for Year-over-Year

• Daily/Weekly/Monthly/Yearly Percent Change

  • percent change from period X to X+1

    • have a view (e.g. facet) for original numbers + percent change

    • % change above line between points ?

    • when viewing only percent change; also show sample size for each period

    • confidence intervals

    • smoothing trend line? only see smoothing trend line?

    • Numeric Aggregation, Color, Facet (if Facet, then can't see original + percent change; only percent change)

    • Facet A) actual Number B) slope / Percent Change C) Slope of Slope i.e. acceleration.

• Only look at Mondays/Tuesday/etc.

Let’s say you’ve doubled from 10,000 to 20,000 users in six months, which means a 15% MoM growth rate. Look closer and an issue pops out: Your growth rate appears to be decelerating. Decelerating growth as your numbers get bigger is a signal that your growth isn’t exponential—it’s probably more linear. Here, it’s more accurate to stick to absolutes by saying that we’re adding 2,000 active users per month instead of saying that we’re growing 15% MoM.
