In the. NET environment, the entire source code of the distribution map of the subordinate functions in fuzzy mathematics is drawn as follows:

Wherein: unit represents the graphic magnification, the larger the number of graphics magnification.

Interval represents the stepping scale, the smaller the value the more accurate (must be 0), but the slower the speed.
