JavaFX 2.1: javafx.scene.chart.StackedBarChart

JavaFX 2.1 introduce a new StackedBarChart class. StackedBarChart is a variation of BarChart that plots bars indicating data values for a category. The bars can be vertical or horizontal depending on which axis is a category axis. The bar for each series is stacked on top of the previous series.
