, HC, NOx, MPH, RPM, AFR and LAMBDA are plotted
against time.
• Gases displayed depend on type of test, but like bar graph mode other gases can
be added to plot.
• Y axis scale can be selected to a chosen gas and its graph will become bolder.
• Cut off limits will be shown on plot for the active series.
• A Landscape graph (only available on the raw data graph view), showing a
complete record of the gas readings, is under the main display. The Main display
seen on the screen will be presented as a window on the landscape graph. To view
readings anywhere through out the test sequence simply click and drag landscape
window. To zoom in or out further on a reading click on arrows in the bottom right
hand corner of the main graph.
• To interrogate gas readings further, hold mouse anywhere in the main graph. A
vertical ‘Wand’ will appear and when held over a reading a ‘INFO’ box (only
available in raw data graph view) will appear. This box will:
1. Display gas values on plot.
2. Give Cut off Status – A green tick indicates all gases are below cut off points, a
red exclamation mark will list all gases above limits whether they are on the plot
or not.
3. Information speech bubble – based on combination of gas readings a suggested
diagnostic hint on what could be wrong with the vehicle will be displayed. Simply
click on bubble to revert to a diagnostic guide.
