When your looking at the log go to "View", "New Chart", on the Horizontal Axis select "RPM", on the Vertical Axis select "Throttle", Under number of steps type in 16, under Chart Content select "A/F". Hit OK.
Now he's the long part. You want to set it up where it looks like your PC software to make tuning a breeze. To do that you'll double click on the numbers in the grey columns and rows and change their values to match the PC software values. Once you've done that, hit "File", "Save Setting as Default". You wont have to enter the values ever again. Just next time when you run a new log you'll hit "View", "New Chart" then instead of hitting OK you'll hit "Default Setting" Easy peasey.
The only other thing that I do once I'm viewing the chart is hit "Colors", check "Color by average value", then go back to "Color" and select "Wobniar". Move the sliders on the left to 15.00 and 10.00. That will show the rich areas in red and the lean areas in blue like on my chart above!
