The function is a product of a project at our school to help students understand these diagrams more deeply and to become handier with MATLAB. The function can be used to plot your own diagrams and draw in some thermodynamic cycle.

Latimer or reduction potential diagrams show the standard reduction potentials connecting various oxidation states of an element. manganese metal is a moderate reducing agent; These diagrams describe the thermodynamic stability of the various species. The information obtained from a Frost diagram is for species under standard conditions (pH=0 for acidic solution and pH=14 for basic solution).
