TERNARY CONTOUR PLOT

TERNARY CONTOUR PLOT

Description:

A ternary plot or a triangle plot, is a barycentric plot on three variables which sum to a constant.
It graphically depicts the ratios of the three variables as positions in an equilateral triangle.

• Contour plots can be used for example to chart the response of an independent variable to changes in a mixture of three components.
• A ternary contour plot has 4 columns of data.
• In a ternary contour plot, the values of the three variables a, b, and c must sum to some constant, K.
  
• The constant is represented as 1.0 or 100%.
  
• Every point on a ternary plot represents a different composition of the three components.
