No able to graph Custom Mag_Field

When I load a Tlog I can graph the throttle but there is no data for mag_field. I have tried multi files and when I select the custom tab and check mag-field there is still no data to graph.

Thanks for any help you guys can provide.

What value do you have your LOG_BITMASK parameter set to?

log_bitmask=131070 I also include a tlog file for review
