Ternary plot

The triangular diagram is one of the forms of representation of the nomograms, ie graphically implemented mathematical equations. It is suitable for displaying a constant sum that is broken down into three summands. Usually it is in the structuring of a value of 100% ( complementary characteristics) used, as for example in the age structure ( division into age groups Vorerwerbs, purchase and retirement). Other examples are the structure of the economy in the three sectors of the economy or the land use ( settlement areas, agricultural and forestry area used, unproductive land ), structure of the agricultural area (arable land, meadows, pastures ) and more.

An advantage of the triangular diagram is that one can represent the development of structural shifts over time and thereby also the structural comparison very clearly.

Parallel multitude will draw Risch being constructed to the sides in an equilateral triangle. It is advisable, either visible to draw the crowds as parallel grid lines in the triangle or draw the lines on the scale lines so long that the construction net inside the triangle is still recognizable.

Has the reason their datum axis in the lower left corner of the triangle, the lower right corner is assigned the value 100, and the scale is a parallel class oriented on the left side of the triangle. The right axis has its origin in the lower right corner, the value 100 in the apex of the triangle, and the values ​​parallels are based on the basic axis. The last value axis is represented by the left side of the triangle. Your zero point is the apex of the triangle, the value 100 in the left corner, and the coordinate lines run parallel to the right side of the triangle.
