Autoscale
Autoscale enables the vertical scale and range to be set automatically, which can make it easier
to keep the live signal(s) visible in the plot. Sometimes, when a measurement doesn't appear as
expected, setting Autoscale to Auto can solve the problem. When autoscale is off, the vertical
scale of the plot can be manually adjusted by a two-finger pinch gesture within the axis label
region of the plot. The range can be adjusted by a single-finger slide gesture within the axis
label region.
