With the same popup menu you can also change the position of the channel scale in the scale
pane.
7.3.2 Zooming in and out on a channel trace
To zoom in on a channel trace
use the Zoom In Tool in the toolbar and click on the channel trace in the graph pane.
To zoom out a channel trace
use the Zoom Out Tool in the toolbar and click on the channel trace in the graph pane.
A magnified channel trace can then be scrolled up or down with the Hand Tool .
Alternatively, you can use the Zoom In, Zoom Out and Hand tools also on the scale of the
channel in the scale pane (3).
If the scale pane shows a group of channels, you can zoom in/out and scroll the entire channel
group at once by using the Zoom Tools or Hand Tool in the scale pane on that channel group.
7.3.3 Smoothing channels
Smoothing can be used to better see trends and is necessary for some calculations (specially
those involving calculating slopes). Smoothing is a running average of a sample of a channel with
its neighbors in time (both before and after). Smoothing should NOT be used to get rid of
excessive noise in a channel, for example spikes caused by ignition misses. Because smoothing
is an averaging operation, the lean-spikes caused by ign. misses would be included in the AFR
values and would bias them towards leaner values.
To smooth a channel either select in the Log window menu:
Channels->Smooth Channel->Channel name
Or right click on the channel trace in the graph pane. The popup menu showing up then also
allows you to smooth the selected channel.
When right clicking on a channel group in the scale pane and selecting smoothing from
there, you can smooth all the channels in the channel group at once.
When selected, the following dialog box will appear:
This allows you to ‘smooth’ a channel. The smoothing slider allows smoothing a trace by
replacing each data point with the running average of its neighbors and itself. The position of the
slider determines how many of the neighbors are included in the running average (0 to 32
neighbors on each side).
