Examples of org.jfree.chart.renderer.category.IntervalBarRenderer.findRangeBounds()

org.jfree.chart.renderer.category.IntervalBarRenderer.findRangeBounds()
Returns the range of values from the specified dataset. For this renderer, this is equivalent to calling findRangeBounds(dataset, true). @param dataset the dataset (null permitted). @return The range (or null if the dataset isnull or empty).
