BESKRIVELSE
The latency test is important when configuring a LinuxCNC system. An adjunct to the standard latency-test latency-histogram plots the distribution of latency. This can be useful to get a feel for how frequent the high latency excursions are.
LinuxCNC and HAL should not be running, stop with halrun -U. Large number of bins and/or small binsizes will slow updates. For single thread, specify --nobase (and options for servo thread). Measured latencies outside of the +/- bin range are reported with special end bars. Use --show to show count for the off-chart [pos|neg] pin.
