layer a group node

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.

l_layer_group(widget, label = "group", parent = "root", index = 0)

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
