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.
