Automatically Re-scaling Plots
By default, VT for Windows attempts to re-scale plots so that the entire plot is visible.
When a re-scale occurs, the high- and low-ranges on the plots are determined by the min
and max statistics for the signal shown on the plot. The monitor plots and the single plot
are re-scaled every time they reach the end of the plot. The loop plots are re-scaled on
every breath.
Automatic re-scaling may be turned off by unchecking the box next to the plot name in
the Plots, Scaling, Auto-Scale menu, as shown below.

Auto-scaling is automatically turned off for a plot if the plot is manually re-scaled. Auto-
scaling can also be turned off by right clicking on a plot and unchecking the Auto-Scale
option.

Plots, Scaling, Auto-Scale function, or clicking the Re-Scale Now
button on the tool bar forces an automatic re-scale to occur immediately.
