When creating a scatter plot using the data investigations scatterplot tool, is there a formula used to figure out what the number for 'Span of smooth' should be? Or is it smaller number rougher line, larger number smoother line?
Thanks,
Brad

Hi @brad_j_crep,
The macro uses R behind the scenes; this article describes smoothing: http://docs.ggplot2.org/current/geom_smooth.html. For "span" they have "Controls the amount of smoothing for the default loess smoother. Smaller numbers produce wigglier lines, larger numbers produce smoother lines."
Hope that helps!
