Re: [Discuss-gnuradio] real-time plotting in gnuradio

[Marcus Müller]

Hi Nikita,

that would sound like you'd need to implement it yourself – and put a lot of thought into how you can make a display that manages to show a (potentially infinite) amount of data on a limited display; probably something like downsampling or only storing the min/max for periods in the signal, depending on what you need to show in that overview.

Cheers,

Marcus

Thanks Julian, I think this should do it for now. In fact, it is quite relevant to what I trying to do.

Also Marcus what should I do if I don't want a "paper ticker" but utility which as you say "constantly rescales" the display?

Hey,

if you are thinking of something like a "paper ticker" like Marcus
mentioned, you could take a look at
[1]. We had an application where we needed to have real time updates
that roll in from right to left.
This could probably be done in a more easy way using the existing QT Gui
Time Sink but we decided to
create a new QT Gui block "rollingscope"  that does just that.
