 Flot plugin for adding panning and zooming capabilities to a plot.
 
-The default behaviour is double click to zoom in, drag to pan. The
-plugin defines plot.zoom({ center }), plot.zoomOut() and
-plot.pan(offset) so you easily can add custom controls. It also fires
-a "plotpan" and "plotzoom" event when something happens, useful for
-synchronizing plots.
