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.

A group layer can contain other layers. If the group layer is invisible, then so are all its children.

Arguments

widget

widget path name as a string

label

label used in the layers inspector

parent

group layer

index

of the newly added layer in its parent group

Value

layer object handle, layer id
