Select the "Zoom Select" toggle button in the toolbar above the diagram area.
The icon changes its background color from black to blue.

range is indicated in an additional zoom line in the channel info area.
Use the "Zoom Reset" icon to restore the original diagram. Alternatively, you can drag
and drop the "Zoom" label from the additional channel info line onto the toolbar but-
ton.
