# Enum: Triangle 




_Which half of a square matrix a layer fills, leaving the other half to a sibling layer, so two quantities read as one image. The conventional way to show a model-vs-data (or data-vs-reconstruction) connectivity matrix. Named for the drawn halves: with the matrix convention (row 0 at top, set invert_y) 'upper' is the top-right triangle._
