3.4.2 Statistics
The Statistics control displays calculated statistics for the selected analysis channel. For multichannel
data captures, only one channel of calculated statistics are displayed at a time and is selected using the
Statistics channel control.
Errors that affect statistical calculations will cause the Plot Error control to appear. Information about er-
rors on specific channels can be accessed by enabling the plot of the channel using the Plot Enable con-
trol and then accessing the Plot Error controls.
3.4.3 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.
