yes I do as well with a wide band sensor.
Post what you have, what it is doing or not doing and what the problem is.

So far this how I made my histogram please correct me if am wrong.
I havent messed with the values yet since I do not know what exactly to do with the error values I get.
on PID I put Air fuel ratio error, units %, decimel 3
filter [SENS.90] > 27
on the Row tab
Table-MAF airflow vs output frequency (Low and High) ,Col sensor Mass airflow freq (units) Hz
Do you have your wideband setup on the aux input pid list ?
That's the most important part . If you have that it will just come together as your trying to make the histogram
Take some screen shots or post your config file
