Plot the mole fraction fcc phase as a function of distance at the end of the heat treatment.

set-plot-condition time last

set-diagram-axis x distance global

set-diagram-axis y npm(fcc)

Instead of explicitly entering the final time it is possible to use the keyword last. The np of npm stands for number of moles of the phase argument and the m is the normalizing quantity (moles). The limits of an axis can be set with the set_scaling_status command. You manually set the scaling of the axis and then restore automatic scaling:

SET_SCALING_STATUS

<X OR Y AXIS>

<USE AUTOMATIC SCALING Y/N>

<IF MANUAL SCALING, ENTER LIMITS>

set-scaling-status x n 1e-3 2e-3

Plot the diagram.

The plot below shows that a single phase fcc zone has formed and this was also observed experimentally, see [1995Eng].
