12.3.3.4 Plot Interval
The plot interval setting determines the width of data traces plotted to the screen. Traces can be
1, 2, 4 or 8 pixels wide.
1, 2, 4 or 8 pixels wide.
The Normal setting for Noggin 250 systems is 2 pixels per trace and the Normal setting the
Noggin 500 and 1000 is 1 pixel per trace.
Noggin 500 and 1000 is 1 pixel per trace.
It can be useful to plot traces narrower than normal to allow more data to fit onto one screen. It
can also be useful to plot traces wider on the screen so that they are easier to see. For example,
when collecting data using the button to trigger the system (see Section 12.2.9: P.76) it is often
preferable to make each trace 4 or 8 pixels wide.

Figure: 12-10 Data traces can be plotted to the screen with a width of 1 pixel (top left), 2 pixels (top right), 4 pixels
(bottom left) or 8 pixels (bottom right). The narrower the trace width, the more data that can be plotted on one screen.
In this example, plotting the data 1 pixel wide results in 16 metres of data displayed on one screen while 2 pixels
results in 8 metres of data, 4 pixels results in 4 metres of data and 8 pixels results in 2 metres of data
Note that the Plot Interval in Noggin
is strictly for display purposes on the DVL screen in real time.
The Plot Interval setting has no effect on the actual data collected and, in fact, data can be
viewed later on the DVL screen with any Plot Interval value. Similarly, data downloaded to a PC
can be plotted using any trace width.
