100% Stacked Column Charts display the comparison of the percentage each part of the
category brings to the whole category, taking the whole category as 100%. Each of the stack components shows
its relative contribution (in percents) to the entire bar and the entity as a whole.
This chart describes products’ sales ratio in several regions. Each region is displayed as a legend item.
You can change the chart by clicking on legend, switching the region data on and off. All legend items that
are currently "on" form one hundred percents, each time you turn on or off an item, the percentage is being
recalculated automatically. Each stacked column represents a product, named in axis labels. X axis is
horizontal and represents categories (cosmetic products), Y axis is vertical and holds the values. Tooltips are
in Union display mode to show data from all series at once.
