Error Bars and Ternary Error Region

Ternary Error Region

  • Generating a ternary chart involves transforming three variables to ratios of three dependent proportions that are plotted in a 2D simplex. Accordingly, the error bar settings defined for individual variables can not be applied independently to a ternary plot.
  • Aabel calculates 33 possible combinations for each ternary data point and uses the convex hull to delineate the resulting error region.
