\brief QwtPlotPanner provides panning of a plot canvas
|
||
|
|
|
||
|
|
QwtPlotPanner is a panner for a plot canvas, that
|
||
|
|
adjusts the scales of the axes after dropping
|
||
|
|
the canvas on its new position.
|
||
|
|
|
||
|
|
Together with QwtPlotZoomer and QwtPlotMagnifier powerful ways
|
||
|
|
of navigating on a QwtPlot widget can be implemented easily.
|
||
|
|
|
||
|
|
\note The axes are not updated, while dragging the canvas
|
||
|
