Thali radar chart : nutrient fingerprint split by category

Draws one radar (spider) panel per nutrient category (proximate, amino acids, minerals, etc.), assembled into a grid with patchwork::patchwork. Each spoke is normalised to [0, 1] using the IFCT-wide maximum for that nutrient, so shapes show how the meal compares to the full diversity of Indian foods.

Usage

thali_plot(
  meals,
  tables = setdiff(.table_names, "edible_oils"),
  title = "Thali nutrient fingerprint",
  base_size = 10,
  ncol = 3L
)

Arguments

meals

A single meal: either a named list from compose_meal() or a named numeric vector forwarded to compose_meal(). For comparison, pass a named list of such objects, e.g. list(Rice = c("Rice" = 150), Dal = c("Bengal gram" = 100)).

tables

Character vector of IFCT table names to include. Defaults to all tables except "edible_oils".

title

Overall plot title.

base_size

Base font size (default 10).

ncol

Number of columns in the panel grid (default 3).

Value

A patchwork object.

Details

Pass a named list of meals to overlay multiple polygons on every panel.

#> ✔ Meal composed: 3 ingredients across 12 tables.

thali_plot(list(
  Rice  = c("Rice" = 150),
  Wheat = c("Wheat flour" = 150)
))
#> ✔ Meal composed: 1 ingredient across 12 tables.
