Hi All, I am currently trying to compare any difference between the QT Time Sink and the QT Vector Sink code. I have a GRC Flowgraph which uses both of these plots. The QT Time Sink works every time, but if I connect a QT Vector Sink at the same point it fails to display data other than zero, although the axis updates as auto range is enabled.
The data feeding the sinks has been decimated down to a slow rate to provide a vector every second. The time sink works updating every second, but the only update on the vector sink is the axis adjusting, and the data remaining at zero. If I simplify the flowgraph to a source, stream to vector and then vector sink it all works fine. I am assuming the GNURadio scheduler must be coping with this setup as the axis on the vector plot update at the right rate, but the data line is fixed at zero. Has anyone else seen this behavior ? I am using version V3.7.9.1. Kind regards, Nigel
