In eulerr: Area-Proportional Euler and Venn Diagrams

Native-unit AABB of one composite tag (label stacked above quantity, annotation stacked below quantity, separated by padding). The geometry matches what setup_tag() renders at draw time, so the size handed to eunoia agrees with the actual on-screen footprint.

Description

Native-unit AABB of one composite tag (label stacked above quantity, annotation stacked below quantity, separated by padding). The geometry matches what setup_tag() renders at draw time, so the size handed to eunoia agrees with the actual on-screen footprint.

Usage

measure_tag(
  label,
  quantity,
  annotation,
  labels_par_id,
  quantities_par_id,
  annotations_par_id,
  labels_gp,
  quantities_gp,
  annotations_gp,
  padding_native
)

Arguments

label, quantity, annotation	the three text components of the tag; any of them may be NULL
labels_par_id, quantities_par_id, annotations_par_id	per-component graphical parameter indices; NA or NULL means the component isn't drawn
labels_gp, quantities_gp, annotations_gp	per-component grid::gpar() lists
padding_native	vertical separation between components, in native units
