The idea of an external legend is, that its layout/design is under the control 
of the application code. This offers a "hack" to put it on the canvas, but 
the design is not tailored for this situation.

Introducing a QwtPlotLegendItem ( see the John's thread about the marker in 
screen coordinates ) is the "clean" solution.
