Get minimal visible value in plot

I am using current version of JFreechart, plot is XYPlot type.

After zooming-in xyplot with

zoomablePlot.zoomDomainAxis(...);
zoomablePlot.开发者_开发问答zoomRangeAxis(...);

I would like to get minimal visible value on domain axis. The DataRange object

//plot is XYPlot type
Range dataRange = plot.getDataRange(...);

contains only 'global' minimum value, not currently displayed.

The following should give you what you want.

plot.getRangeAxis().getLowerBound();
