How to retrieve dBs values on PostFeko into a text file

Hello!

I would like to know if there is a way to retrieve the dB values of a cartesian view (according X,Y or Z axis) into a text file or another type of file.

I am working with a Lua script so I can avoid to do all the things manually.

I already use GetSetData to print the number of sample points of my fields according the axis but I don't know how I can see the dB values related to X,Y,Z and frequency values.

Thank you by advance!
