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

org.jfree.chart.renderer.category.StatisticalBarRenderer.findRangeBounds()
Returns the range of values the renderer requires to display all the items from the specified dataset. This takes into account the range between the min/max values, possibly ignoring invisible series. @param dataset the dataset (null permitted). @return The range (or null if the dataset isnull or empty).
