7.4 Displaying Harmonic Trends

During recording, the X-axis is automatically scaled so that the full time series graph fits on the screen.
Once recording has stopped and the X-axis scale has been changed so that the waveforms do not fit on
the screen, you can scroll through the time series graph by moving left and right.
You can search for the time the event occurred (event marker).
The start time and stop time event markers are always displayed.
Synchronization is achieved with an event selected from the event list.

• The white band on the scroll bar indicates
the range of measured values that can be
displayed. When this band does not include
the cursor position, the cursor and cursor
value are not displayed.
• The cursor on the scroll bar shows where
the cursor is located relative to all measure-
ment data.
