Show Data for Trace #2
If a second data file is overlaid on the graph, selecting this option will cause the
numeric display to show data from Trace #2, the second log file that was overlaid on
the analysis graph.
Show Difference Data (Trace #2 – Trace #1)
If a second data file is overlaid on the graph, selecting this option will cause the
numeric display to show differences in the two files, shown as (Trace #2 – Trace
#1).
Right Clicking on the Numerical Display Table brings up a channel editing menu
which contains the following options:
Show/Hide Channel
This menu option will toggle the visibility of the currently selected channel. If the
channel is currently displayed on the graph, it will be hidden. If it is not displayed on
the graph, the graph will be redrawn with the current active channel displayed.
Show/Hide ALL Channels
This option will toggle the visibility of ALL the data channels drawn on the graph. If
any channels are displayed, this menu item will hide all the channels. If no channels
are visible, the graph will be redrawn with all the channels displayed.
Edit Channel
This menu option will allow you to edit the limits for each data channel, change the
trace color for each channel, and hide the channel if you do not want it to be
displayed on the graph.
Changing the Minimum/Maximum and Slope/Offset values for a data channel offers
the ability to individually magnify the data values for each channel on the analysis
graph. For example, if your recorded engine speed was never greater than 6000
RPM, it would be a good idea to change the maximum value from the default of
12750 RPM to 6500 RPM. This would cause the Engine Speed data trace to span
almost the entire vertical range of the graph, multiplying the resolution of the signal
for analysis purposes.
Use the Save Cfg… button at the lower left of the screen to save your current
channel configuration to a file.
Use the Load Cfg button to load a preset configuration and apply it to the current
log data being analyzed.
Use the Make Default button to save the current configuration as your default
configuration.
[Data Channels]
These will be one menu item for each channel of data that has been recorded by the
Engine Analyzer. To change the data source for the currently selected channel,
simply pick another data source and the new data will be displayed in the current
position on both the numeric table and the data graph.
