\brief 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.
