     * \brief A graphical sink to display multiple signals on a
     * time_raster plot.
     * \ingroup instrumentation_blk

     *
     * \details
     * This is a QT-based graphical sink that takes in byte
     * streams and plots a time_raster (spectrogram) plot.
     *
     * Input stream: This expects a bit stream (0, 1 in the LSB of a
     * byte). It will display packed bytes but the display will have
     * to be autoscaled.
     *
     * The sink supports plotting streaming byte/char data or
     * messages. The message port is named "in". The two modes cannot
     * be used simultaneously, and \p nconnections should be set to 0
     * when using the message mode. GRC handles this issue by
     * providing the "Float Message" type that removes the streaming
     * port(s).
     *
     * This sink can plot messages that contain either uniform vectors
     * of byte/char values (pmt::is_{u,s}32vector) or PDUs where the
     * data is a uniform vector of byte/char values.
