The term state diagram comes from systems theory . It refers to the graphic representation of states and related changes of state. It is used in several areas:

  • In computer science , the state transition diagram is a form of representation to show the control flow of programs in the form of states and state transitions.
  • In computer science, there is also a state diagram (UML) in UML .
  • In materials science , chemistry and physics , a state diagram provides information about the phase composition of a material and is closely linked to the respective equation of state, if one exists. This plot is sometimes called a phase diagram .
  • In astrophysics , the states (luminosity, spectral class, etc.) of the stars are entered in the Hertzsprung-Russell diagram .
  • In pneumatics and hydraulics , see function diagram .
