[Presentation of multidimensional observed vectors in the form of trigonometric functions, explained by means of an example from internal medicine].

In the present paper a method of the graphic representation of multivariate data is described which depicts the vectors of the measuring values in form of trigonometric functions. The usefulness of this form of representation is demonstrated with the help of a material of medical data from the field of diseases of the thyroid gland. Here a comparison with the representation of multidimensional vectors of the observed values in form of graphs or in form of transformation into the plane emphasizes the good perceptibility of particularities of the data.
