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