Bar Charts use horizontal bars to demonstrate a comparison over categories. One axis represents values and another one stands for the discrete value. 3D Bar Charts differ from 2D Bar Charts only with its appearance, as a 3D series has some depth but no sensible third-dimension axis. Stacked Bars are usually used when you want to show several amounts that are parts of a whole amount.
This Chart has two series, representing the amount of cosmetic products bought by men and women. Negative values are used here to show the men's purchases part: the "null" point is in the center of the chart and if the X-Axis, as the axis values grow in both sides. The maximum value of both sides of the X-Axis is $18 000. There are two Y-Axes representing the cosmetic products. The legend is enabled in the chart, so you can disable and enable any of the series. Tooltips show only the sales volumes on the both sides or each stacked bar for men and women separately.
