 * \ingroup qtgui_blk
 *
 * This is a QT-based graphical sink the takes set of a complex
 * streams and plots them in the time domain. For each signal, both
 * the signal's I and Q parts are plotted, and they are all plotted
 * with a different color, and the \a set_title and \a set_color
 * functions can be used to change the lable and color for a given
 * input number.
