Detailed Description¶
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.
