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)
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 |
layer object handle, layer id
