slicetree

slicetree, tile type

The slicetree is an interactive tile that offers navigation controls to pick a slice.

table P = with
  [| as Family, as Subfamily, as Product, as Price |]
  [| "Garment", "Clothing", "Pant",   25 |]
  [| "Garment", "Clothing", "Shirt",  15 |]
  [| "Garment", "Accessory", "Hat",   12 |]
  [| "Home", "Furniture", "Table",    75 |]
  [| "Home", "Accessory", "Tabletop",  7 |]

table Slices[slice] = slice by P.Product title: P.Product

Slices.Family = same(P.Family)
Slices.Subfamily = same(P.Subfamily)
Slices.Product = same(P.Product)

show slicetree "My tree selector" a1b4 with
  Slices.Family
  Slices.Subfamily
  Slices.Product

show table "Selected product" c1d4 slices:slice with
  P.Product
  P.Price

In the above script, the slicetree introduces a hierarchy with 3 levels.

The slicetree supports an arbitrary number of hierarchical levels. Each extra level comes as an extra text vector being added to the tile block. The tile gets a tuple (level 1, level 2, .., level n) of text values obtained for each slice. Empty text values (i.e. "") are not allowed.

This tile creates a tree structure: a first level of nodes for each (level 1) value, a second level of nodes for each (level 1, level 2) value, and so on.

For every distinct tuple (level 1, level 2, .., level n), the tile selects exactly one tile among all the slices that matche the tuple. If the slice dimension itself is (implicitely) used as the last level, then there is no ambiguity.

The slicetree tile offers the possibly to reorder the hierarchical levels through the order by tile option:

table P = with
  [| as Family, as FC, as Subfamily, as SC, as Product, as Price |]
  [| "Garment", 2,     "Clothing",  11,      "Pant",     25 |]
  [| "Garment", 2,     "Clothing",  11,      "Shirt",    15 |]
  [| "Garment", 2,     "Accessory", 12,      "Hat",      12 |]
  [| "Home",    1,     "Furniture", 13,      "Table",    75 |]
  [| "Home",    1,     "Accessory", 14,      "Tabletop",  7 |]

table Slices[slice] = slice by P.Product title: P.Product

Slices.Family = same(P.Family)
Slices.FC = same(P.FC)
Slices.Subfamily = same(P.Subfamily)
Slices.SC = same(P.SC)
Slices.Product = same(P.Product)

show slicetree "My tree selector" a1b4 with
  Slices.Family
  Slices.Subfamily
  Slices.Product
  order by [Slices.FC, Slices.SC, Slices.Product]

show table "Selected product" c1d4 slices:slice with
  P.Product
  P.Price

The ordering applies to the table Slices and must be consistent with the construction of the tree. In practice, specifying the ordering through a tuple aligned with the tree levels - as done in the above script - ensures the consistency of the ordering.
