A Trace View displays periodic data (i.e. the 50Hz sampled channels) plotted against time.
The configuration dialog shows a list of channels which will be graphed.
To add a channel, click on the green + button. A dialog comes up showing the list of channels available for that session. If you wish to add a channel that wasn't logged in that session, click on Show all channels check-box.
To remove a channel, select it by clicking on the channel name, and clock on the red x button
A trace view can contain more than one graph, and each graph may contain more than one channel. The way in which the channels are grouped is determined by the drop-down 'Display' box:
The order of the channels in the dialog box determines the order in which they are displayed in the Trace View from top to bottom. The order of channels can be changed using the Up and Down arrow buttons.
Each channel has options for displaying additional information. To bring up these options, either double click on a channel name, or highlight a channel and click on the Axis settings... button.
As a keyboard shortcut, the settings for each of these may be toggled by pressing CTRL-A, CTRL-G, CTRL-O or CTRL-V.
If a graph contains more than one channel that contains the same scaling (e.g. in a sculling boat, the port and starboard channels for force), then it reduces the amount of clutter in the display if only one of them has 'Axis' selected.
In the 'Rower Selection' area of the dialog, you may set whether the pane shows data for all those rowers selected in the Rower Bar, or you can force it to show data for specified rowers.
The X-axis is labelled in seconds. There is an option to force the trace view to automatically align to the current stroke. In this instance, the start of the stroke (as determined by the first rower's force to exceed the catch threshold) is positioned at '0 seconds', and a short period - the 'Stroke pre-trigger duration' - is included to the left.
Full control of the X-Axis can be set up through a dialog. To bring this up:
This dialog contains settings for:
Additionally, the width of the X-axis can be changed by zooming in or out (keyboard short-cuts '+' and '-'), and the 'Align to Strokes' feature can be accessed from the View menu.
Note that all panes configured as Trace Views share the same settings for the X-axis. They cannot be configured independently.
The trace view displays other features along the top of the pane:
By default, the graphs are drawn in a thin line, just one pixel wide. This is best for clarity and for maximum drawing speed. If greater visibility is required, then the width of the lines can be increased:
Once a line width has been selected, it can be toggled on and off using View→Thick Lines on Graphs.
Thick lines are particularly useful when running real-time telemetry. However, the display may appear to run very slowly if there are many graphs on display.
