The Waveform Plot has features that enable you to zoom in and out on the

To display any or all the signals for the waveform plots menu, you can use the
following options:

into the area of interest. Define the area of interest using the mouse and selecting
the zoom in area. The entire upper half of the oscilloscope displays the selected
