The attached files enable the JFreeCharts to be panned. They must implement the Pannable interface. An example implementation have been added for the XYPlot.
To enable the panning just call
PannableChartPanel chartPanel = ....
and use the PannableXYPlot.
Someone might find some nice mouse gestures to use the panning.
I would be happy if this is integrated to JFreeChart.
