The point-plot Little App provides a quick path to making data graphics. Select the data set, the response and explanatory variables, and you’re there.

  • You can map color to a covariate and can facet the graph (as shown above) by another covariate.
  • Works with both quantitative and categorical variables on either or both axes, for color, and for faceting.
  • Can jitter categorical variables
  • Set transparency to handle overplotting in large data sets.
  • Can overlay violin density plots. (Quantitative variables are divided into 3 groups for this, color, and faceting.)
  • Has a measurement ruler.
