Racepak O2 sensor

My plots look backward compare to what everybody
Is explaining The first plot was in 3500' air and the second
Was 300' air. No changes in the car at all.
The graph index for A/F is 10 to 15 at the top of the graph
The first plot has a 12.8 reading at top of 1-2 gear change
The second plot has a reading 12.1 at 1-2 gear change

Plots show lean in the worst air of the two. Am I looking
at correctly. [15 lean. 10 rich]. ? This is why I am confused by readings

Couldn't upload a higer resolution pictures

Thanks
David
