Loon's displays that are based on Cartesian coordinates (i.e. scatterplot, histogram and graph display) allow for layering visual information including polygons, text and rectangles.

---|---|
x | x coordinates |
y | y coordinates |
color | fill color, if empty string |
linecolor | outline color |
linewidth | linewidth of outline |
label | label used in the layers inspector |
