Stacked Bar Charts are usually used when it is necessary to show several series of the similar data when you need to show that those values for one point form a whole. A 100% Stacked Chart means that whatever the whole value is, it will be taken as 100% for the category. 3D is only a visual effect that gives no additional information.
This Chart is a demonstration of the top 9 cosmetic products sales in four regions: Florida, Texas, Arizona and Nevada. The whole profit from sales is taken as 100% for each product, so the Y-Axis with ticks of 25% demonstrates the percentage. The X-Axis is responsible for the categories and rotated vertically. The legend allows to enable/disable the series, but whichever series are enabled the whole their profit amount will equal 100%. A 3D effect is a visual setting that is defined by using the bar3d() method and hold no additional information. The tooltips in the chart are set in the "union" mode and they show the category name as a title and all values with series names in the body parts. All values in tooltips are displayed in dollars.
