Dear all, I'm implementing a GUI to show the time-varying wireless channel gain with qtgui.
To be specific, I want to implement is a history plot. The X-axis is discrete time and the Y-axis is a channel gain. And the plot should be updated (refreshed) every few seconds. ( for example http://qwt.sourceforge.net/cpuplot.png ) I've tried with qtgui.sink_f() block. But, the basic option 'plottime' is not appropriate for this purpose. Is there any other way to implement it? * Minsuk Kang *
