Examples of org.jfree.chart.plot.Zoomable

org.jfree.chart.plot.Zoomable
A plot that is zoomable must implement this interface to provide a mechanism for the {@link ChartPanel} to control the zooming.

                // here we tweak the notify flag on the plot so that only
                // one notification happens even though we update multiple
                // axes...
                boolean savedNotify = p.isNotify();
                p.setNotify(false);
                Zoomable z = (Zoomable) p;
                if (z.getOrientation() == PlotOrientation.HORIZONTAL) {
                    z.zoomDomainAxes(vLower, vUpper, plotInfo, selectOrigin);
                    z.zoomRangeAxes(hLower, hUpper, plotInfo, selectOrigin);
                }
                else {
                    z.zoomDomainAxes(hLower, hUpper, plotInfo, selectOrigin);
                    z.zoomRangeAxes(vLower, vUpper, plotInfo, selectOrigin);
                }
                p.setNotify(savedNotify);
            }
