 * \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 set of a floating
 * point streams and plots a time_raster (spectrogram) plot.
 *
 * The sink supports plotting streaming float 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 float 32 values (pmt::is_f32vector) or PDUs where the data
 * is a uniform vector of float 32 values.
