The rate of change of frequency can be plotted in the old plot program, PSSPLT, by selecting function # 17 "time derivative".

Below I plot the frequency and the ROCOF for the speed of machine 101 NUC-A in savnw network after trip a machine 3011.

PSSPLT is a part of PSSE package so you should find it in the installation folder.
