Automatically Re-scaling a Plot
By default, the VT for Windows software attempts to re-scale plots so that the entire plot
is visible to you. When a re-scale occurs, the software determines the high- and low-
ranges on the plots by the min and max statistics for the signal shown on the plot. The
monitor plots and the single plot re-scale every time they reach the end of the plot. The
software re-scales the loop plots on every breath.
You may turn off the automatic re-scaling for an individual plot by unchecking the box
next to the plot's name (Plot Æ Rescale Æ Auto Re-scale.) The software automatically
turns auto-scaling off for a plot if you manually re-scale that plot.
Clicking the Re-scale button on the toolbar forces an automatic re-scale of all plots to
occur immediately.
