3.4.2 Statistics
The Statistics control displays calculated statistics for the analysis. Errors that affect statistical calcula-
tions will cause the Plot Error control to appear. Information about errors can be accessed by accessing
the Plot Error controls.

3.4.3 Plot Enable
The Plot Enable control is disabled for CDB5378. One channel operation only.
3.4.4 Cursor
The Cursor control is used to identify a point on the graph using the mouse and then display its plot values.
When any point within the plot area of the graph is clicked, the Cursor will snap to the closest plotted point
and the plot values for that point display below the graph. When using the Zoom function, the Cursor is
used to select the corners of the area to zoom.
