[Discuss-gnuradio] QT Vector sink question? |

Hello all,
Thanks for all the interesting discussion. Very educational.
I’ve got a pair of questions concerning the QT vector sink.
My application uses the vector sink for plotting and diagnostics
of averaged spectra.
I’m getting the impression that the QT vector sink is using a good fraction
of my computer resources, despite trying to reduce the update intervals.
My question is 1) can I somehow turn off the Min and Max functions and any
averaging of the data in the QT vector plotter?
The second question concerns a waterfall plot for the vectors I’m
generating. The QT waterfall plot does not accept a vector.
If I turn the vector back into a stream, then the QT waterfall plot then
Fourier transforms the spectra back. making a mess.
So the Second question: 2) is there a way to provide the QT water fall plotter
with a Vector and not have it FFT the data?
Thanks
Glen
