ORDINATE
Function:
This
command allows the user to select which thermodynamic function
is to be plotted on the y-axis of the graph produced using PLOT !.
Either the thermodynamic function of the whole system can be
plotted, or (by specifying a component name) the partial molar
thermodynamic function of one of the components. By using the
LIMITS parameter, the user can also select the range of values to be
plotted. This command, together with the ABSCISSA_SET LIMITS command
allows the user to enlarge portions of the graph and
hence be able to inspectcomplicated parts of the graph in greater detail.

Parameter
values:
|
GIBBS_ENERGY
|
takes the values
COMPONENT(*)/ SYSTEM/ EXCESS
|
|
This specifies that the function to be plotted on the y-axis of the graph is to be the Gibbs energy.
|
|
ENTHALPY
|
takes the values
COMPONENT(*)/ SYSTEM/ EXCESS
|
|
This specifies that the function to be plotted on the y-axis of the graph is to be the enthalpy.
|
|
ACTIVITY
|
takes the value COMPONENT(*)
|
|
This specifies that the function to be plotted on the y-axis of the graph is to be the activity.
|
|
GAMMA
|
takes the values COMPONENT(*)
|
|
This specifies that the function to be plotted on the y-axis of the graph is to be gamma (the activity coefficient).
|
|
PARTIAL_GE
|
takes the values COMPONENT(*)
|
|
This specifies that the function to be plotted on the y-axis of the graph is to be the partial excess Gibbs energy.
|
|
ENTROPY
|
takes the values COMPONENT(*)/ SYSTEM
|
|
This specifies that the function to be plotted on the y-axis of the graph is to be the entropy.
|
|
LIMITS
|
takes the values
AUTO/ <MINIMUM,MAXIMUM>
|
|
This parameter enables the user to specify the range of values to be plot on the y-axis of the graph. The maximum and minimum values can either be set manually or AUTO can be selected (this is the default) in which case the computer sets the range of values automatically. |
|
EXCESS_ENTROPY
|
takes the values COMPONENT(*)/ SYSTEM
|
|
This specifies that the function to be plotted on the y-axis of the graph is to be the excess entropy.
