Hi,

Can the time axis (y-axis) of the qt-gui waterfall sink be set as desired? By default, it only shows a duration of 20 seconds. I would like this to be adjusted,  for example, to 1 minute or two minutes, etc.

I'm compiling the waterfall sink directly from C++ (I'm not using python or GRC).

Thanks in advance.

Khalid,

Fair question and a feature others have asked about. You can't do that right now, but it's something we should enable. It's definitely doable, but I think last I looked, it wasn't trivial (the way QWT handles rastor images and how we inherit from them and set up the data etc., just a lot of moving pieces).
