[Discuss-gnuradio] Meaning of Center Frequency in QT GUI Sink / QT Waterfall Sink

[Volker Schroer]

Hi,

what is the meaning of the variable "Center Frequency" in the 
qt_gui_sink / qt_waterfall_sink ?

If I remember well, in pre 3.7 version it served as base of the  x - 
axis legend.

Now, if I choose a value > bandwidth/2 the spectrum will not be displayed.

Do I misinterpret the meaning  of "Center Frequency" or is this a bug ?
