<a class="el" href="class_qwt_plot_panner.html">QwtPlotPanner</a> provides panning of a plot canvas.
33
<a class="el" href="class_qwt_plot_panner.html">QwtPlotPanner</a> is a panner for a <a class="el" href="class_qwt_plot_canvas.html">QwtPlotCanvas</a>, that adjusts the scales of the axes after dropping the canvas on its new position.<p>

Together with <a class="el" href="class_qwt_plot_zoomer.html">QwtPlotZoomer</a> and <a class="el" href="class_qwt_plot_magnifier.html">QwtPlotMagnifier</a> powerful ways of navigating on a <a class="el" href="class_qwt_plot.html">QwtPlot</a> widget can be implemented easily.<p>
