Hello,

What do the various traces on the AI studio Gas Data Channel represent? 

Thank you.

Hello avfe,

Did you use the BME board to record the data? It is gas data channel in you attached picture.
If you had BME board, did you refer BME AI-Studio document? https://www.bosch-sensortec.com/media/boschsensortec/downloads/application_notes_1/bst-bme688-an001....

I used the BME688 development kit to record the data, and took a screenshot of the figure from the AI studio. On page 20, the documentation indicates that there are 10 data points for gas channel data. However, the documentation does not provide specifics on the different data points. Do you know where I can find further documentation on how to interpret the data? 

Thank you!
