 KPlotWidget is a QWidget-derived class that provides a virtual base class
 for easy data-plotting. The idea behind KPlotWidget is that you only have
 to specify information in "data units"; i.e., the natural units of the
 data being plotted. KPlotWidget automatically converts everything
 to screen pixel units.
