I also tested the ternary diagram, as constructed here, extensively, and the data points plot exactly where they should be (see for instance the first three diagrams (Fig.

As per Step 2, the triangle/ternary diagram has then been stretched, so it looks like an equilateral triangle again, which doesn’t affect the XY coordinate system behind it, as it is stretched with it.Ĭorrespondingly, due to the projection of A to Y (100 units), a factor of 0.86603 comes into play: tan(30°) = 0.57735 -> 0.57735 x 0.86603 = 0.5. 7).īecause A is projected to 100 units (rather than 86.60…), the triangle is elongated and the angle of 30 degrees changes to 26.56505 degrees unfortunately, Excel doesn’t plot diagrams in scale to show this. Each corner of the triangle corresponds to a pure component. To display three variables in a ternary graph, their values must be normalized to a constant, usually either 1 or 100. As a ternary diagram represents three different substances, it is a three-dimensional plot drawn on a two-dimensional plane. A ternary or triangular diagram (chart/plot/graph) is a graphical way to display the relationship between three variables or components. Move the black dot to any location within the triangle by clicking on that location which represents the overall composition of the mixture. Now, you have understood some basics of a ternary diagram. Thus, we can use the normalized A component as Y without a trigonometric function (Fig. This Demonstration shows two representations of a ternary phase diagram which is used to represent the phase behavior of three-component mixtures. The ternary diagram ABC is projected into a cartesian XY graph.įor an equilateral triangle with a side length of 100 units (e.g., X-axis B-C side 0-100%), the height is 86.60254 units (i.e., Y-axis A).Ī is projected onto Y with 100 units. I have been using OriginLab to plot ternary phase diagrams but I want to replace it with an open source package that may have more decent capabilities in that sense. In the case here, however, it is a different approach: Using the blank ternary graph to the right, plot the. A ternary graph is a triangle with each side representing one of the three main components of the whole. Made by faculty at the University of Kentucky and produced by the University of Colorado Boulder, De. A ternary plot, ternary graph, triangle plot, simplex plot, Gibbs triangle or de Finetti diagram is a barycentric plot on three variables which sum to a constant.

Also, to calibrate the diagram, make sure to plot: 0,0,100. The equations I used were: xC÷SIN(RADIANS(60))+A÷TAN(RADIANS(60)))×SIN(RADIANS(60) yA×SIN(RADIANS(60)) For a,b, and c as endmembers of the ternary diagram. You are right with the tan(30°) statement for calculating the X coordinate in an equilateral triangle/ternary diagram. Develops a ternary phase diagram using equilibrium data. I would hide the axis, labels and put a blank ternary diagram in the background, over which my data would be plotted.
