[time-nuts] Lady Heather Question

[Mark Sims]

When you are viewing a time interval that is longer than one second per screen pixel,  the program must sub-sample the data.  Every second the screen is redrawn with a new set of samples.  Also the plots are rescaled according to the data being plotted (if auto-scaling is turned on).  With very noisy data,  like the raw oscillator plot,  you see the effects of what amounts to a new data set every second.   Turning on display filtering (F D command) helps smooth out the changes (but can hide very short disturbances).
