# <MaskYTrack> Element

The element's content enables or disables tracking between the Y1 and Y2 levels. Tracking ON links the y-axis scaling of the logic 0 and 1 levels. For example, if the logic 1 level increases, the logic 0 level increases by the same amount. The contents can be OFF or ON (default value).

The element sets the <MaskScaleMode> to XONLY. It also sets the Logic Levels Track setting in the Mask Test Scaling dialog box (Measure > Mask Tests > Mask Test Scaling...).
