Off

If this is checked, no auto-refreshing is performed. But if a measurement is performed or inserted, it will be plotted. Refreshing must be done manually using Plot->Refresh Active or Plot->Refresh All. Set auto-refresh in Off modus if you wish to perform manual refreshing as will be described below. But note that if the settings in Plot->Chart Settings for Active Plot... are changed, this will immediately change the settings in the active plot.
