5.3 Axonometric diagram of the fuzzy histogram

For one-dimensional data the characterizing functions of the fuzzy relative frequencies are constant on the classes Kj. Therefore it is possible to depict them in an axonometric way. One axis is the axis on which the classes are defined. The second axis is the independent variable y for the characterizing function ηj(·) of the fuzzy relative frequency hn*(Kj). The third axis is the axis for the values ηj(y).

An example of the axonometric picture of a fuzzy histogram is given in Figure 5.4.
