Plot Condition and Independent Variable
There are two free variables after a simulation is done by the DICTRA module. One is the simulation TIME and the other is a DISTANCE in the system.
In general, when plotting a diagram you MUST set either type as fixed, i.e. the plot condition, use command SET_PLOT_CONDITION. The plot condition chosen is printed on a separate line above the diagram.
The other variable is then the independent variable, use command SET_INDEPENDENT_VARIABLE. The independent variable is used as stepping variable. It varies along the calculated curve.

TIME
: Integration timeDISTANCE
: Distance in the system. It can be a GLOBAL distance counted from the rightmost interface of the system. A LOCAL distance is counted from the LOWER interface of the specific region prompted for.INTERFACE
: At a certain interface. An interface is identified by the NAME of the adjacent region, with the addition that you will be prompted to specify if the interface is at the upper or lower end of the region.INTEGRAL
: Is automatically SET when using an INTEGRAL VARIABLE as axis variable.TIE_LINE
: At a certain interface. Allows you to plot a certain quantity from both sides of an interface. The typical application is for plotting tie-lines.

TIME
: Integration time. Is automatically SET when using an INTEGRAL VARIABLE' or TIME as axis variable.DISTANCE
: Space coordinate. It may be GLOBAL. It is then counted from the rightmost interface of the system. Alternatively, it may be LOCAL. The distance is then counted from the LOWER interface of the specific region prompted for.
