NAME¶

latency-plot - another way to view latency numbers

SYNOPSIS¶

latency-plot [-?|--help] [-H|--hal] [-b|--base nS] [-s|--servo nS] [-t|--time mS] [--relative] [--actual]

DESCRIPTION¶

latency-plot makes a strip chart recording for a base and a servo thread. It may be useful to see spikes in latency when other applications are started or used. Mainly superseded by latency-histogram.

LinuxCNC and HAL should not be running, stop with halrun -U.
