In the preferences, this branch is named 2D Y-Axis. In the properties, it is named Y-axis and is displayed below the color axis branch.

The 2D Y-axis in the 2D view of a trend graph represents the elements, zones or "tracks" of a vector signal. For a transverse profile measurement of flatness or strip tension in the steel industry, for instance, the 2D Y-axis measures the strip width.

The zone scaling can be set in a manner of counting (zones 1 to n) by Zone width =1.

It can also represent a physical dimension by entering the real width of a zone, e.g. of a flatness measurement roll.

Example

A flatness measurement roll has 64 measurement zones represented by a vector with 64 signals. Each zone has a width of 20 mm. Thinking in meters, enter 0.02 as the zone width value and the 2D Y-axis will automatically shift from 0 to 1.28, corresponding to the real width of the measurement roll.
