3.2.1.6 Zooming and Panning

When the Auto-scroll and Automatically fit Y check boxes are checked, the last samples will be shown and the Y axis will be zoomed such that all values will be visible.

For manually zooming in or out or inspecting a region in more detail, disable these options and zoom and pan using the mouse.
