Since V1.7, it is possible to plot eye diagrams. Eye diagram plotting is started when setting the 'eye diagram period' inside the 'plot options' - dialog. This dialog pops up when you try to change settings inside the plot pindow. Setting this entry to a value unequal '(none)' processes that data which will be plotted in a way that an eye-diagram can be seen on the plot result window.
An eye diagram plot can be seen in the picture 3.9.
