Scanner Histogram display question

[torchredfrc]

I am curious about the histogram display in VCM Scanner... What are the x & y axis numbers showing in all the tabs? I seem to be running really rich and I would like to adjust but I'm not 100% sure what I am looking at with the data given in the histogram. Also, I have 1.4.0 installed and have seen several pictures of the histogram display windows around. They all have the extra Air/Fuel ratio tab. Why does my version not include this? I understand that 1.5 will be including added capability for AFR but since it is not out, where are all these other people obtaining the version that can display the narrow band data in the histogram? I am very interested in seeing this data in a histogram table.

Ok, I think I've figured some of this out actually...

I gather this:

The advance/retard histogram relates to the Main Spark vs. Airflow, vs RPM open throttle (high & low octane) tables and the LTFT/STFT histogram relates to the Primary VE Percent vs RPM vs MAP table.

Now my question is this... how do I know which table the car is running on (high vs. low octane) based on the histogram display or other displays in the scanner software. Also, if I want to lean out a certain field in the VE table, do I need to add or subtract from the data in the table?
