Stacked Column Charts display the comparison of the quantitative value each part of the category brings to the whole category. Each of the stack components shows its relative contribution to the entire bar and the entity as a whole.
This Stacked Column Chart with Negative values demonstrates loss and profit from selling several products in several states. While the revenue is normally positive or absent, profit can be negative, so here is a situation when some of the products bring negative profit (which is correctly to be called a loss) for a company. The zero point is marked by a horizontal line marker, it helps to see where the values start. Vertical grid is enabled to give more attention to each stacked column as a separate entity. The horizontal X axis is duplicated, so the names are shown both at the top and the bottom of the chart.
Each legend item represents a series, which holds the values for a state. When legend item is hovered or clicked, the corresponding series is hovered or turned on/off (depending on the current state). When we hover a column, its tooltip is shown up and shows all the values for all regions, having the product name as a title.
