Dynamically Rescale Based on Selected Threads Enable to rescale the vertical axis of the graph to the maximum memory usage in the entire graph by the threads currently checked in the CPU load table. When disabled, rescale the vertical axis to the maximum memory usage of all threads in the entire graph. The default settings is disabled.
