Hi abtisam,

The main reason for this problem you didn't select detector signals.

when we don't selecAdd t signal detector we never see baseline chromatogram,to solve this problem from online plot for FID signal Click on change than from Edit signal plot remove FID signal from Available signals(left side) to selected signals( right side) by Click on Add than Click on Ok. like blow image.

I hope this help you to solve the problem.

Regards,

Dheya
