\brief QwtPolarPanner provides panning of a polar plot canvas
|
|
|
|
QwtPolarPanner is a panner for a QwtPolarCanvas, that
|
|
adjusts the visible area after dropping
|
|
the canvas on its new position.
|
|
|
|
Together with QwtPolarMagnifier individual ways
|
|
of navigating on a QwtPolarPlot widget can be implemented easily.
