Selecting the Time Axis
In waveform views, the horizontal axis can be displayed either in absolute
time with date and time stamps, or in milliseconds relatively to the
beginning of a waveform.
To change the time units, click on the waveform window with the right
mouse button, select Options..., click on the Axes tab, select the desired
units, and then click OK.
Selecting Line Styles and Colors

The minimum distance between the two markers is exactly one cycle.
To change the marker position, click on the button, or click on the

click on the point where you want to put the marker.
You can also drag both markers with the mouse, or use the right and left

the graph line by clicking on the graph to the left or right from the
reference point.
To disable delta measurements, click on the Delta button once again.
Using a Zoom
You can use a horizontal and, for waveforms, also a vertical, zoom to
change size of your graph.
