Hi Muhammad,
"straightforward" depends on your expectations. But no, in the Qt
Frequency Sink itself that is not possible.
There is the gr-inspector [1] OOT, which will automatically detect
signals, has a graphical sink to display these labeled etc. Output looks
like attached.
Seems to work well under GNU Radio 3.10, but you'll have to apply my
patches (as of today, [2] is unmerged – if anyone care to review that
code...)
git clone https://github.com/gnuradio/gr-inspector
git pull --rebase https://github.com/marcusmueller/gr-inspector.git
build_on_main
and then go through the usual OOT installation.
Best regards,
Marcus

Dear GNU Radio Community,
I am currently working on a project that involves spectrum analysis
using GNU Radio Companion. I am utilizing the QT GUI Frequency Sink
block to display the frequency spectrum. I would like to know if there
is a straightforward way to automatically detect, mark, and label the
magnitudes of frequency peaks in the spectrum display without moving
the mouse on these frequency peaks.
Any suggestions or guidance on how to achieve this would be greatly
appreciated.
Thank you for your assistance.
Best regards,
Muhammad Anas
