12 Using the Zoom information pane to study details in the echogram
If you need to magnify a part of the echogram to study details, you can use the Zoom information pane.
Context
The Zoom information pane allows you to magnify a chosen area of the current echogram. Once the Zoom information pane is opened, the zoomed area is shown as a dotted rectangle in the view. You can change the size of the zoomed area, and you can move the rectangle anywhere inside the active view.

In this screen capture, the zoomed area rectangle is positioned close to the Zoom information pane. You can however place the pane and the zoomed area independently anywhere you like inside the active view.
