QwtPlotMagnifier::QwtPlotMagnifier(QWidget*canvas)[explicit]
       Constructor

       Parameters:canvas Plot canvas to be magnified

QwtPlotMagnifier provides zooming, by magnifying in steps.

       Using QwtPlotMagnifier a plot can be zoomed in/out in steps using keys, the mouse wheel or moving a mouse
       button in vertical direction.

       Together with QwtPlotZoomer and QwtPlotPanner it is possible to implement individual and powerful
       navigation of the plot canvas.
